+# UCP.NET - Universal Commerce Protocol for .NET
+
+[](LICENSE)
+[](https://www.nuget.org/packages/UCP.NET/)
+
+A .NET client library for [Universal Commerce Protocol (UCP)](https://ucp.dev) - enabling seamless commerce integrations with standardized APIs for checkout, payments, and order management.
+
+## Overview
+
+UCP.NET is a comprehensive .NET library that provides an easy-to-use client for integrating with UCP-compliant commerce platforms. It supports the full UCP specification including:
+
+- ✅ **Checkout Sessions** - Create and manage shopping cart checkout flows
+- ✅ **Payment Processing** - Handle payment methods and credentials securely
+- ✅ **Order Management** - Track orders from creation to fulfillment
+- ✅ **Discovery** - Automatic capability discovery from merchant endpoints
+- ✅ **Extensible** - Support for UCP extensions and custom capabilities
+
+## Installation
+
+Install the NuGet package:
+
+```bash
+dotnet add package UCP.NET
+```
+
+Or via Package Manager Console:
+
+```powershell
+Install-Package UCP.NET
+```
+
+## Quick Start
+
+### Basic Setup
+
+```csharp
+using UCP.NET.Client;
+using UCP.NET.Configuration;
+using UCP.NET.Extensions;
+
+// Configure services
+services.AddUcpShoppingClient(options =>
+{
+ options.BaseUrl = "https://merchant.example.com/ucp";
+ options.ApiKey = "your-api-key";
+ options.ProtocolVersion = "2026-01-11";
+});
+```
+
+### Using Configuration File
+
+In `appsettings.json`:
+
+```json
+{
+ "UcpClient": {
+ "BaseUrl": "https://merchant.example.com/ucp",
+ "ApiKey": "your-api-key",
+ "ProtocolVersion": "2026-01-11",
+ "TimeoutSeconds": 30
+ }
+}
+```
+
+Then register the client:
+
+```csharp
+services.AddUcpShoppingClient(configuration);
+```
+
+### Creating a Checkout Session
+
+```csharp
+public class CheckoutService
+{
+ private readonly IUcpShoppingClient _ucpClient;
+
+ public CheckoutService(IUcpShoppingClient ucpClient)
+ {
+ _ucpClient = ucpClient;
+ }
+
+ public async Task CreateCheckoutAsync()
+ {
+ var request = new CheckoutCreateRequest
+ {
+ Ucp = new UcpMetadata
+ {
+ Version = "2026-01-11",
+ Capabilities = new List
+ {
+ new Capability { Name = "checkout" }
+ }
+ },
+ LineItems = new List
+ {
+ new LineItem
+ {
+ Id = "item-123",
+ Quantity = 2,
+ Item = new ItemInfo
+ {
+ Name = "Product Name",
+ Description = "Product Description",
+ ImageUrl = "https://example.com/image.jpg"
+ }
+ }
+ }
+ };
+
+ var response = await _ucpClient.CreateCheckoutAsync(request);
+ return response.Id;
+ }
+}
+```
+
+### Updating a Checkout Session
+
+```csharp
+public async Task UpdatePaymentAsync(string checkoutId)
+{
+ var updateRequest = new CheckoutUpdateRequest
+ {
+ Ucp = new UcpMetadata { Version = "2026-01-11" },
+ Payment = new PaymentUpdate
+ {
+ PaymentHandler = new PaymentHandler
+ {
+ Id = "payment-handler-123",
+ Name = "Credit Card"
+ }
+ }
+ };
+
+ var response = await _ucpClient.UpdateCheckoutAsync(checkoutId, updateRequest);
+}
+```
+
+### Completing a Checkout
+
+```csharp
+public async Task CompleteCheckoutAsync(string checkoutId)
+{
+ var order = await _ucpClient.CompleteCheckoutAsync(checkoutId);
+ Console.WriteLine($"Order created: {order.Id}");
+ return order;
+}
+```
+
+## Clean Architecture Example
+
+Check out the complete [Clean Architecture example](examples/UCP.CleanArchitecture/) demonstrating:
+
+- **Domain Layer** - Core business entities and interfaces
+- **Application Layer** - Use cases implemented with MediatR
+- **Infrastructure Layer** - UCP client integration
+- **API Layer** - ASP.NET Core Web API
+
+### Example Structure
+
+```
+examples/UCP.CleanArchitecture/
+├── src/
+│ ├── Domain/ # Entities, Value Objects, Interfaces
+│ ├── Application/ # Use Cases, DTOs, MediatR Commands/Queries
+│ ├── Infrastructure/ # UCP Integration, Repositories
+│ └── API/ # ASP.NET Core Web API
+└── tests/
+ ├── Application.Tests/
+ └── Infrastructure.Tests/
+```
+
+## Features
+
+### Type-Safe Models
+
+All UCP schema types are mapped to strongly-typed C# classes with proper JSON serialization:
+
+```csharp
+public class CheckoutResponse
+{
+ public required UcpMetadata Ucp { get; set; }
+ public required string Id { get; set; }
+ public required string State { get; set; }
+ public List? LineItems { get; set; }
+ public PaymentResponse? Payment { get; set; }
+ public FulfillmentResponse? Fulfillment { get; set; }
+ public OrderSummary? OrderSummary { get; set; }
+}
+```
+
+### Error Handling
+
+The client throws detailed exceptions for error scenarios:
+
+```csharp
+try
+{
+ var checkout = await _ucpClient.GetCheckoutAsync("invalid-id");
+}
+catch (HttpRequestException ex)
+{
+ // Handle HTTP errors (4xx, 5xx)
+ Console.WriteLine($"HTTP Error: {ex.Message}");
+}
+catch (InvalidOperationException ex)
+{
+ // Handle null responses
+ Console.WriteLine($"Invalid response: {ex.Message}");
+}
+```
+
+### Dependency Injection
+
+Full support for .NET dependency injection:
+
+```csharp
+// Startup.cs or Program.cs
+builder.Services.AddUcpShoppingClient(options =>
+{
+ options.BaseUrl = builder.Configuration["UcpClient:BaseUrl"]!;
+ options.ApiKey = builder.Configuration["UcpClient:ApiKey"];
+});
+
+// Use in controllers
+public class CheckoutController : ControllerBase
+{
+ private readonly IUcpShoppingClient _ucpClient;
+
+ public CheckoutController(IUcpShoppingClient ucpClient)
+ {
+ _ucpClient = ucpClient;
+ }
+}
+```
+
+## Configuration Options
+
+| Option | Type | Description | Default |
+|--------|------|-------------|---------|
+| `BaseUrl` | string | Base URL of the UCP endpoint | Required |
+| `ApiKey` | string | API key for authentication | null |
+| `BearerToken` | string | Bearer token for authorization | null |
+| `ProtocolVersion` | string | UCP protocol version | "2026-01-11" |
+| `TimeoutSeconds` | int | Request timeout in seconds | 30 |
+| `IncludeDetailedErrors` | bool | Include detailed error messages | true |
+| `CustomHeaders` | Dictionary | Custom headers for all requests | {} |

Universal Commerce Protocol (UCP)
-
-
-
- An open standard enabling interoperability between various commerce
- entities to facilitate seamless commerce integrations.
-
-
-
- Documentation |
- Specification |
- Discussions
-
-
-## Overview
-
-The Universal Commerce Protocol (UCP) addresses a fragmented commerce landscape
-by providing a standardized common language and functional primitives. It
-enables platforms (like AI agents and apps), businesses, Payment Service
-Providers (PSPs), and Credential Providers (CPs) to communicate effectively,
-ensuring secure and consistent commerce experiences across the web.
-
-With UCP, businesses can:
-
-* **Declare** supported capabilities to enable autonomous discovery by
- platforms.
-* **Facilitate** secure checkout sessions, with or without human intervention.
-* **Offer** personalized shopping experiences through standardized data
- exchange.
-
-## Why UCP?
-
-As commerce becomes increasingly agentic and distributed, the ability for
-different systems to interoperate without custom, one-off integrations is vital.
-UCP aims to:
-
-* **Standardize Interaction:** Provide a uniform way for platforms to interact
- with businesses, regardless of the underlying backend.
-* **Modularize Commerce:** Breakdown commerce into distinct **Capabilities**
- (e.g., Checkout, Order) and **Extensions** (e.g., Discounts,
- Fulfillment), allowing for flexible implementation.
-* **Enable Agentic Commerce:** Designed from the ground up to support AI
- agents acting on behalf of users to discover products, fill carts, and
- complete purchases securely.
-* **Enhance Security:** Support for advanced security patterns like AP2
- mandates and verifiable credentials.
-
-### Key Features
-
-* **Composable Architecture:** UCP defines **Capabilities** (such as
- "Checkout" or "Identity Linking") that businesses implement to enable easy
- integration. On top of that, specific **Extensions** can be added to enhance
- the consumer experience without bloating the capability definitions.
-* **Dynamic Discovery:** Businesses declare their supported Capabilities in a
- standardized profile, allowing platforms to autonomously discover and
- configure themselves.
-* **Transport Agnostic:** The protocol is designed to work across various
- transports. Businesses can offer Capabilities via REST APIs, MCP (Model
- Context Protocol), or A2A, depending on their infrastructure.
-* **Built on Standards:** UCP leverages existing open standards for payments,
- identity, and security wherever applicable, rather than reinventing the
- wheel.
-* **Developer Friendly:** A comprehensive set of SDKs and libraries
- facilitates rapid development and integration.
-
-## Key Capabilities
-
-The initial release focuses on the essential primitives for transacting:
-
-* **Checkout:** Facilitates checkout sessions including cart management and
- tax calculation, supporting flows with or without human intervention.
-* **Identity Linking:** Enables platforms to obtain authorization to perform
- actions on a user's behalf via OAuth 2.0.
-* **Order:** Webhook-based updates for order lifecycle events (shipped,
- delivered, returned).
-* **Payment Token Exchange:** Protocols for PSPs and Credential Providers to
- securely exchange payment tokens and credentials.
-
-## Getting Started
-
-* 📚 **Explore the Documentation:** Visit [ucp.dev](https://ucp.dev) for a
- complete overview, the full protocol specification, tutorials, and guides.

+# UCP.NET - Universal Commerce Protocol for .NET
+
+[](LICENSE)
+
+A comprehensive .NET implementation of the [Universal Commerce Protocol (UCP)](https://ucp.dev) - enabling seamless commerce integrations for .NET developers.
+
+## 🎯 Overview
+
+This repository provides both a NuGet package and a Clean Architecture example for integrating UCP into .NET applications. UCP is forked from Google's Universal Commerce Protocol specification and adapted for the .NET ecosystem.
+
+**What is UCP?**
+Universal Commerce Protocol (UCP) is an open standard that enables interoperability between various commerce entities, providing a standardized way to handle checkout, payments, orders, and fulfillment.
+
+## 📦 UCP.NET Library
+
+The core `UCP.NET` library provides:
+- ✅ **Strongly-typed models** for all UCP types (Checkout, Payment, Order, Fulfillment)
+- ✅ **HTTP client** for UCP REST APIs
+- ✅ **Dependency injection** extensions
+- ✅ **Async/await** support throughout
+- ✅ **Configuration** via appsettings.json or code
+
+### Installation
+
+```bash
+dotnet add package UCP.NET
+```
+
+### Quick Start
+
+```csharp
+// Configure in Startup.cs or Program.cs
+builder.Services.AddUcpShoppingClient(options =>
+{
+ options.BaseUrl = "https://merchant.example.com/ucp";
+ options.ApiKey = "your-api-key";
+});
+
+// Inject and use
+public class CheckoutService
+{
+ private readonly IUcpShoppingClient _ucpClient;
+
+ public CheckoutService(IUcpShoppingClient ucpClient)
+ {
+ _ucpClient = ucpClient;
+ }
+
+ public async Task CreateCheckout()
+ {
+ var request = new CheckoutCreateRequest
+ {
+ Ucp = new UcpMetadata { Version = "2026-01-11" },
+ LineItems = new List
+ {
+ new LineItem
+ {
+ Id = "product-123",
+ Quantity = 2
+ }
+ }
+ };
+
+ return await _ucpClient.CreateCheckoutAsync(request);
+ }
+}
+```
+
+For complete API documentation, see [README_NUGET.md](README_NUGET.md).

+# UCP Clean Architecture Example
+
+This example demonstrates how to integrate UCP.NET into a Clean Architecture application using MediatR for CQRS pattern implementation.
+
+## Architecture
+
+The solution follows Clean Architecture principles with clear separation of concerns:
+
+```
+├── Domain/ # Core business entities and interfaces
+├── Application/ # Use cases, DTOs, and MediatR commands/queries
+├── Infrastructure/ # UCP client integration and repositories
+└── API/ # ASP.NET Core Web API
+```
+
+## Layers
+
+### Domain Layer
+Contains the core business entities and repository interfaces:
+- `ShoppingCart` - Shopping cart entity
+- `Order` - Order entity
+- `IShoppingCartRepository` - Repository interface for shopping carts
+- `IOrderRepository` - Repository interface for orders
+
+### Application Layer
+Contains the business logic implemented as MediatR commands and queries:
+- **Commands:**
+ - `CreateCheckoutCommand` - Create a new checkout session
+ - `AddItemToCartCommand` - Add items to cart
+ - `SyncCheckoutWithUcpCommand` - Sync local cart with UCP
+ - `CompleteOrderCommand` - Complete checkout and create order
+- **Queries:**
+ - `GetCartQuery` - Retrieve cart by ID
+
+### Infrastructure Layer
+Implements repository interfaces and integrates with UCP:
+- `InMemoryShoppingCartRepository` - In-memory storage for carts
+- `InMemoryOrderRepository` - In-memory storage for orders
+- UCP.NET client configuration
+
+### API Layer
+Provides RESTful endpoints:
+- `POST /api/checkout` - Create new checkout
+- `GET /api/checkout/{id}` - Get checkout by ID
+- `POST /api/checkout/{id}/items` - Add item to cart
+- `POST /api/checkout/{id}/sync-ucp` - Sync with UCP
+- `POST /api/orders/complete?cartId={id}` - Complete order
+
+## Running the Example
+
+1. Configure UCP endpoint in `appsettings.json`:
+
+```json
+{
+ "UcpClient": {
+ "BaseUrl": "https://your-merchant-endpoint.com/ucp",
+ "ApiKey": "your-api-key",
+ "ProtocolVersion": "2026-01-11"
+ }
+}
+```
+
+2. Run the API:
+
+```bash
+cd src/API
+dotnet run
+```
+
+3. Open Swagger UI at `https://localhost:5001/swagger`
+
+## Example Workflow
+
+1. **Create Checkout:**
+```bash
+curl -X POST "https://localhost:5001/api/checkout?userId=user123"
+```
+
+2. **Add Items to Cart:**
+```bash
+curl -X POST "https://localhost:5001/api/checkout/{cartId}/items" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "productId": "product-123",
+ "name": "Example Product",
+ "quantity": 2,
+ "unitPrice": 29.99
+ }'
+```
+
+3. **Sync with UCP:**
+```bash
+curl -X POST "https://localhost:5001/api/checkout/{cartId}/sync-ucp"
+```
+
+4. **Complete Order:**
+```bash
+curl -X POST "https://localhost:5001/api/orders/complete?cartId={cartId}"
+```
+
+## Key Features
+
+### Clean Architecture Benefits
+- ✅ **Testability** - Each layer can be tested independently
+- ✅ **Maintainability** - Clear separation of concerns
+- ✅ **Flexibility** - Easy to swap implementations (e.g., use real database instead of in-memory)
+
+### MediatR Integration
+- ✅ **CQRS Pattern** - Separate commands and queries
+- ✅ **Decoupling** - Controllers don't depend on concrete implementations
+- ✅ **Pipeline Behaviors** - Easy to add cross-cutting concerns
+
+### UCP Integration
+- ✅ **Seamless Integration** - UCP client injected via DI
+- ✅ **Type Safety** - Strongly-typed models
+- ✅ **Async/Await** - Full async support
+
+## Technology Stack
+
+- .NET 8.0
+- ASP.NET Core Web API
+- MediatR 12.4.1
+- UCP.NET (local reference)
+- Swagger/OpenAPI
+
+## Next Steps
+
+To use this as a starting point for your own application:
+
+1. Replace in-memory repositories with real database (e.g., Entity Framework Core)
+2. Add authentication and authorization
+3. Implement validation using FluentValidation
+4. Add logging and error handling middleware
+5. Implement additional UCP capabilities (payments, fulfillment, etc.)

+# Getting Started with UCP.NET
+
+This guide will walk you through setting up and using UCP.NET in your .NET applications.
+
+## Prerequisites
+
+- .NET 8.0 SDK or later
+- A UCP-compliant merchant endpoint (or use the example mock for testing)
+- Visual Studio 2022, VS Code, or Rider (optional)
+
+## Installation
+
+### Option 1: NuGet Package (Coming Soon)
+
+```bash
+dotnet add package UCP.NET
+```
+
+### Option 2: Build from Source
+
+```bash
+git clone https://github.com/sahinhurcan/ucp.NET.git
+cd ucp.NET
+dotnet build src/UCP.NET/UCP.NET.csproj
+```
+
+Then reference the project in your application:
+
+```xml
+
+```
+
+## Quick Start
+
+### 1. Configure the UCP Client
+
+In your `appsettings.json`:
+
+```json
+{
+ "UcpClient": {
+ "BaseUrl": "https://your-merchant-endpoint.com/ucp",
+ "ApiKey": "your-api-key-here",
+ "ProtocolVersion": "2026-01-11",
+ "TimeoutSeconds": 30
+ }
+}
+```
+
+### 2. Register Services in Dependency Injection
+
+In `Program.cs` or `Startup.cs`:
+
+```csharp
+using UCP.NET.Extensions;
+
+var builder = WebApplication.CreateBuilder(args);
+
+// Add UCP client
+builder.Services.AddUcpShoppingClient(builder.Configuration);
+
+// Or configure inline
+builder.Services.AddUcpShoppingClient(options =>
+{
+ options.BaseUrl = "https://merchant.example.com/ucp";
+ options.ApiKey = "your-api-key";
+ options.ProtocolVersion = "2026-01-11";
+});
+
+var app = builder.Build();
+```
+
+### 3. Use the Client
+
+```csharp
+using UCP.NET.Client;
+using UCP.NET.Models;
+
+public class CheckoutService
+{
+ private readonly IUcpShoppingClient _ucpClient;
+
+ public CheckoutService(IUcpShoppingClient ucpClient)
+ {
+ _ucpClient = ucpClient;
+ }
+
+ public async Task CreateAndCompleteCheckout()
+ {
+ // 1. Create checkout
+ var createRequest = new CheckoutCreateRequest
+ {
+ Ucp = new UcpMetadata
+ {
+ Version = "2026-01-11",
+ Capabilities = new List
+ {
+ new Capability { Name = "checkout" }
+ }
+ },
+ LineItems = new List
+ {
+ new LineItem
+ {
+ Id = "product-123",
+ Quantity = 2,
+ Item = new ItemInfo
+ {
+ Name = "Example Product",
+ Description = "A sample product"
+ }
+ }
+ }
+ };
+
+ var checkout = await _ucpClient.CreateCheckoutAsync(createRequest);
+ Console.WriteLine($"Checkout created: {checkout.Id}");
+
+ // 2. Update checkout (e.g., add payment info)
+ var updateRequest = new CheckoutUpdateRequest
+ {
+ Ucp = new UcpMetadata { Version = "2026-01-11" },
+ Payment = new PaymentUpdate
+ {
+ PaymentHandler = new PaymentHandler
+ {
+ Id = "payment-handler-123",
+ Name = "Credit Card"
+ }
+ }
+ };
+
+ var updated = await _ucpClient.UpdateCheckoutAsync(
+ checkout.Id,
+ updateRequest);
+
+ // 3. Complete checkout
+ var order = await _ucpClient.CompleteCheckoutAsync(checkout.Id);
+ Console.WriteLine($"Order created: {order.Id}");
+
+ return order.Id;
+ }
+}
+```
+
+## Example Scenarios
+
+### Scenario 1: Simple Product Purchase
+
+```csharp
+// Create checkout with a single product
+var request = new CheckoutCreateRequest
+{
+ Ucp = new UcpMetadata { Version = "2026-01-11" },
+ LineItems = new List
+ {
+ new LineItem
+ {
+ Id = "SKU-001",
+ Quantity = 1,
+ Item = new ItemInfo
+ {
+ Name = "Laptop",
+ Description = "15-inch Laptop",
+ Url = "https://store.example.com/laptop",
+ ImageUrl = "https://store.example.com/laptop.jpg"
+ }
+ }
+ }
+};
+
+var checkout = await _ucpClient.CreateCheckoutAsync(request);
+```
+
+### Scenario 2: Adding Multiple Items
+
+```csharp
+var items = new List
+{
+ new LineItem
+ {
+ Id = "SKU-001",
+ Quantity = 2,
+ Item = new ItemInfo { Name = "Mouse" }
+ },
+ new LineItem
+ {
+ Id = "SKU-002",
+ Quantity = 1,
+ Item = new ItemInfo { Name = "Keyboard" }
+ }
+};
+
+var request = new CheckoutCreateRequest
+{
+ Ucp = new UcpMetadata { Version = "2026-01-11" },
+ LineItems = items
+};
+
+var checkout = await _ucpClient.CreateCheckoutAsync(request);
+```
+
+### Scenario 3: Retrieving Checkout Status
+
+```csharp
+var checkoutId = "checkout-session-123";
+var checkout = await _ucpClient.GetCheckoutAsync(checkoutId);
+
+Console.WriteLine($"Checkout State: {checkout.State}");
+Console.WriteLine($"Total Items: {checkout.LineItems?.Count ?? 0}");
+
+if (checkout.OrderSummary != null)
+{
+ Console.WriteLine($"Subtotal: {checkout.OrderSummary.Subtotal?.Display}");
+ Console.WriteLine($"Tax: {checkout.OrderSummary.Tax?.Display}");
+ Console.WriteLine($"Total: {checkout.OrderSummary.Total?.Display}");
+}
+```

+`examples/UCP.CleanArchitecture/`
+
+This example demonstrates:
+- Domain-Driven Design
+- CQRS with MediatR
+- Dependency Injection
+- Repository pattern
+- RESTful API with Swagger
+
+To run the example:
+
+```bash
+cd examples/UCP.CleanArchitecture/src/API
+dotnet run
+```
+
+Then navigate to `https://localhost:5001/swagger` to explore the API.
+
+## Error Handling
+
+```csharp
+try
+{
+ var checkout = await _ucpClient.GetCheckoutAsync("invalid-id");
+}
+catch (HttpRequestException ex) when (ex.StatusCode == System.Net.HttpStatusCode.NotFound)
+{
+ Console.WriteLine("Checkout not found");
+}
+catch (HttpRequestException ex)
+{
+ Console.WriteLine($"HTTP error: {ex.StatusCode} - {ex.Message}");
+}
+catch (InvalidOperationException ex)
+{
+ Console.WriteLine($"Invalid operation: {ex.Message}");
+}
+catch (Exception ex)
+{
+ Console.WriteLine($"Unexpected error: {ex.Message}");
+}
+```
+
+## Configuration Options
+
+| Option | Type | Description | Default | Required |
+|--------|------|-------------|---------|----------|
+| `BaseUrl` | string | UCP endpoint base URL | - | ✅ Yes |
+| `ApiKey` | string | API key for authentication | null | ❌ No |
+| `BearerToken` | string | Bearer token for authorization | null | ❌ No |
+| `ProtocolVersion` | string | UCP protocol version | "2026-01-11" | ❌ No |
+| `TimeoutSeconds` | int | Request timeout | 30 | ❌ No |
+| `IncludeDetailedErrors` | bool | Include detailed error messages | true | ❌ No |
+| `CustomHeaders` | Dictionary | Additional HTTP headers | empty | ❌ No |
+
+## Next Steps
+
+1. **Explore the API**: Review the [complete API documentation](README_NUGET.md)
+2. **Check the Example**: Study the [Clean Architecture example](examples/UCP.CleanArchitecture/)
+3. **Read UCP Specification**: Understand the protocol at [ucp.dev](https://ucp.dev)
+4. **Join the Community**: Participate in [GitHub Discussions](https://github.com/sahinhurcan/ucp.NET/discussions)
+
+## Troubleshooting
+
+### Issue: "Unable to connect to UCP endpoint"
+
+**Solution**: Verify the `BaseUrl` in your configuration and ensure the endpoint is accessible.
+
+### Issue: "Unauthorized" or "Forbidden" errors
+
+**Solution**: Check your `ApiKey` or `BearerToken` configuration.
+
+### Issue: "Package 'UCP.NET' could not be found"
+
+**Solution**: The NuGet package is not yet published. Build from source for now.
+
+### Issue: Model validation errors
+
+**Solution**: Ensure all required properties are set. Check the UCP specification for required fields.

+# Repository Implementation Note
+
+These repositories use static ConcurrentDictionary for in-memory storage as a simple demonstration.
+
+**For Production Use:**
+- Replace with proper database implementation (Entity Framework Core, Dapper, etc.)
+- Use scoped or transient lifetime for repositories
+- Implement proper data persistence
+- Add transaction support
+
+**Current Limitations:**
+- Data is shared across all application instances
+- Data is lost on application restart
+- Not suitable for multi-instance deployments
+- Not thread-safe across multiple processes
+
+This is intentional for the example to keep dependencies minimal and focus on architecture patterns.

-# Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, gender identity and expression, level of
-experience, education, socio-economic status, nationality, personal appearance,
-race, religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or
- advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic
- address, without explicit permission
-* Disrespecting the community's time by sending spam or other unsolicited
- commercial messages
-* Other conduct which could reasonably be considered inappropriate in a
- professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, or to ban temporarily or permanently any
-contributor for other behaviors that they deem inappropriate, threatening,
-offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-This Code of Conduct also applies outside the project spaces when the Project
-Steward has a reasonable belief that an individual's behavior may have a
-negative impact on the project or its community.
-
-## Conflict Resolution
-
-We do not believe that all conflict is bad; healthy debate and disagreement
-often yield positive results. However, it is never okay to be disrespectful or
-to engage in behavior that violates the project’s code of conduct.
-
-If you see someone violating the code of conduct, you are encouraged to address
-the behavior directly with those involved. Many issues can be resolved quickly
-and easily, and this gives people more control over the outcome of their
-dispute. If you are unable to resolve the matter for any reason, or if the
-behavior is threatening or harassing, report it. We are dedicated to providing
-an environment where participants feel welcome and safe.
-
-Reports should be directed to ucp-coc-external@google.com, the
-Project Steward(s) for UCP. It is the Project Steward’s duty to
-receive and address reported violations of the code of conduct. They will then
-work with a committee consisting of representatives from the Open Source
-Programs Office and the Google Open Source Strategy team. If for any reason you
-are uncomfortable reaching out to the Project Steward, please email
-.
-
-We will investigate every complaint, but you may not receive a direct response.
-We will use our discretion in determining when and how to follow up on reported
-incidents, which may range from not taking action to permanent expulsion from
-the project and project-sponsored spaces. We will notify the accused of the
-report and provide them an opportunity to discuss it before any action is taken.
-The identity of the reporter will be omitted from the details of the report
-supplied to the accused. In potentially harmful situations, such as ongoing
-harassment or threats to anyone's safety, we may take action without notice.
-
-## Attribution
-
-This Code of Conduct is adapted from the Contributor Covenant, version 1.4,
-available at

-
-## Contribution Process
-
-### Code Reviews
-
-All submissions, including submissions by project members, require review. We
-use [GitHub pull requests](https://docs.github.com/articles/about-pull-requests)
-for this purpose.
-
-### Pull Request Titles and Commit Messages
-
-This repository enforces **Conventional Commits** for Pull Request titles.
-Your PR title must follow this format: `type: description`. If your change
-is a breaking change (e.g., removing a schema field or file), you **must**
-add `!` before the colon: `type!: description`.
-
-**Common Types:**
-
-- `feat`: A new feature
-- `fix`: A bug fix
-- `docs`: Documentation only changes
-- `style`: Changes that do not affect the meaning of the code
-- `refactor`: A code change that neither fixes a bug nor adds a feature
-- `perf`: A code change that improves performance
-- `test`: Adding missing tests or correcting existing tests
-- `chore`: Changes to the build process or auxiliary tools and libraries
-
-**Examples:**
-
-- `feat: add new payment gateway`
-- `fix: resolve crash on checkout`
-- `docs: update setup guide`
-- `feat!: remove deprecated buyer field from checkout`
-
-### Linting and Automated Checks
-
-We use linters and automated checks to maintain code quality and consistency.
-These checks run automatically via GitHub Actions when you open a pull request.
-Your pull request must pass all checks before it can be merged.
-
-You can run many of these checks locally before committing by installing and
-using `pre-commit`:
-
-```bash
-pip install pre-commit
-pre-commit install
-```
-
-This will set up pre-commit hooks to run automatically when you `git commit`.
-
-### Submitting a Pull Request
-
-1. Fork the repository and create your branch from `main`.
-2. Make your changes, ensuring you follow the setup instructions below.
-3. If you've installed `pre-commit`, it will run checks as you commit.
-4. Ensure your pull request title follows the Conventional Commits format.
-5. Fill out the pull request template in GitHub, providing details about
- your change.
-6. Push your branch to GitHub and open a pull request.
-7. Address any automated check failures or reviewer feedback.
-
-## Local Development Setup
-
-### Spec Development
-
-1. Make relevant updates to JSON files in `source/`
-2. Run `python generate_schemas.py` to generate updated files in `spec/`
-3. Check outputs from step above to ensure deltas are expected. You may need to
- extend `generate_schemas.py` if you are introducing a new generation concept
-
-To validate JSON and YAML files format and references in `spec/`, run
-`python validate_specs.py`.
-
-If you change any JSON schemas in `spec/`, you must regenerate any SDK client
-libraries that depend on them. For example, to regenerate Python Pydantic
-models run `bash sdk/python/generate_models.sh`. Our CI system runs
-`scripts/ci_check_models.sh` to verify that models can be generated
-successfully from the schemas.
-
-It is also important to go through documentation locally whenever spec files
-are updated to ensure there are no broken references or stale/missing contents.
-
-### Documentation Development
-
-1. Ensure dependencies are installed: `pip install -r requirements-docs.txt`
-2. Run the development server: `mkdocs serve --watch spec`
-3. Open **http://127.0.0.1:8000** in your browser
-4. Before submitting a pull request with documentation changes, run
- `mkdocs build --strict` to ensure there are no warnings or errors. Our CI
- build uses this command and will fail if warnings are present (e.g.,
- broken links).
-
-### Using a virtual environment (Recommended)
-
-To avoid polluting your global environment, use a virtual environment. Prefix
-the virtual environment name with a `.` so the versioning control systems don't
-track pip install files:
-
-```bash
-$ sudo apt-get install virtualenv python3-venv
-$ virtualenv .ucp # or python3 -m venv .ucp
-$ source .ucp/bin/activate
-(.ucp) $ pip install -r requirements-docs.txt
-(.ucp) $ mkdocs serve --watch spec
-(.ucp) $ deactivate # when done
-```

-# Getting Started with UCP.NET
-
-This guide will walk you through setting up and using UCP.NET in your .NET applications.
-
-## Prerequisites
-
-- .NET 8.0 SDK or later
-- A UCP-compliant merchant endpoint (or use the example mock for testing)
-- Visual Studio 2022, VS Code, or Rider (optional)
-
-## Installation
-
-### Option 1: NuGet Package (Coming Soon)
-
-```bash
-dotnet add package UCP.NET
-```
-
-### Option 2: Build from Source
-
-```bash
-git clone https://github.com/sahinhurcan/ucp.NET.git
-cd ucp.NET
-dotnet build src/UCP.NET/UCP.NET.csproj
-```
-
-Then reference the project in your application:
-
-```xml
-
-```
-
-## Quick Start
-
-### 1. Configure the UCP Client
-
-In your `appsettings.json`:
-
-```json
-{
- "UcpClient": {
- "BaseUrl": "https://your-merchant-endpoint.com/ucp",
- "ApiKey": "your-api-key-here",
- "ProtocolVersion": "2026-01-11",
- "TimeoutSeconds": 30
- }
-}
-```
-
-### 2. Register Services in Dependency Injection
-
-In `Program.cs` or `Startup.cs`:
-
-```csharp
-using UCP.NET.Extensions;
-
-var builder = WebApplication.CreateBuilder(args);
-
-// Add UCP client
-builder.Services.AddUcpShoppingClient(builder.Configuration);
-
-// Or configure inline
-builder.Services.AddUcpShoppingClient(options =>
-{
- options.BaseUrl = "https://merchant.example.com/ucp";
- options.ApiKey = "your-api-key";
- options.ProtocolVersion = "2026-01-11";
-});
-
-var app = builder.Build();
-```
-
-### 3. Use the Client
-
-```csharp
-using UCP.NET.Client;
-using UCP.NET.Models;
-
-public class CheckoutService
-{
- private readonly IUcpShoppingClient _ucpClient;
-
- public CheckoutService(IUcpShoppingClient ucpClient)
- {
- _ucpClient = ucpClient;
- }
-
- public async Task CreateAndCompleteCheckout()
- {
- // 1. Create checkout
- var createRequest = new CheckoutCreateRequest
- {
- Ucp = new UcpMetadata
- {
- Version = "2026-01-11",
- Capabilities = new List
- {
- new Capability { Name = "checkout" }
- }
- },
- LineItems = new List
- {
- new LineItem
- {
- Id = "product-123",
- Quantity = 2,
- Item = new ItemInfo
- {
- Name = "Example Product",
- Description = "A sample product"
- }
- }
- }
- };
-
- var checkout = await _ucpClient.CreateCheckoutAsync(createRequest);
- Console.WriteLine($"Checkout created: {checkout.Id}");
-
- // 2. Update checkout (e.g., add payment info)
- var updateRequest = new CheckoutUpdateRequest
- {
- Ucp = new UcpMetadata { Version = "2026-01-11" },
- Payment = new PaymentUpdate
- {
- PaymentHandler = new PaymentHandler
- {
- Id = "payment-handler-123",
- Name = "Credit Card"
- }
- }
- };
-
- var updated = await _ucpClient.UpdateCheckoutAsync(
- checkout.Id,
- updateRequest);
-
- // 3. Complete checkout
- var order = await _ucpClient.CompleteCheckoutAsync(checkout.Id);
- Console.WriteLine($"Order created: {order.Id}");
-
- return order.Id;
- }
-}
-```
-
-## Example Scenarios
-
-### Scenario 1: Simple Product Purchase
-
-```csharp
-// Create checkout with a single product
-var request = new CheckoutCreateRequest
-{
- Ucp = new UcpMetadata { Version = "2026-01-11" },
- LineItems = new List
- {
- new LineItem
- {
- Id = "SKU-001",
- Quantity = 1,
- Item = new ItemInfo
- {
- Name = "Laptop",
- Description = "15-inch Laptop",
- Url = "https://store.example.com/laptop",
- ImageUrl = "https://store.example.com/laptop.jpg"
- }
- }
- }
-};
-
-var checkout = await _ucpClient.CreateCheckoutAsync(request);
-```
-
-### Scenario 2: Adding Multiple Items
-
-```csharp
-var items = new List
-{
- new LineItem
- {
- Id = "SKU-001",
- Quantity = 2,
- Item = new ItemInfo { Name = "Mouse" }
- },
- new LineItem
- {
- Id = "SKU-002",
- Quantity = 1,
- Item = new ItemInfo { Name = "Keyboard" }
- }
-};
-
-var request = new CheckoutCreateRequest
-{
- Ucp = new UcpMetadata { Version = "2026-01-11" },
- LineItems = items
-};
-
-var checkout = await _ucpClient.CreateCheckoutAsync(request);
-```
-
-### Scenario 3: Retrieving Checkout Status
-
-```csharp
-var checkoutId = "checkout-session-123";
-var checkout = await _ucpClient.GetCheckoutAsync(checkoutId);
-
-Console.WriteLine($"Checkout State: {checkout.State}");
-Console.WriteLine($"Total Items: {checkout.LineItems?.Count ?? 0}");
-
-if (checkout.OrderSummary != null)
-{
- Console.WriteLine($"Subtotal: {checkout.OrderSummary.Subtotal?.Display}");
- Console.WriteLine($"Tax: {checkout.OrderSummary.Tax?.Display}");
- Console.WriteLine($"Total: {checkout.OrderSummary.Total?.Display}");
-}
-```
-
-## Clean Architecture Example
-
-For a complete example showing Clean Architecture with MediatR, see:
-`examples/UCP.CleanArchitecture/`
-
-This example demonstrates:

-Then navigate to `https://localhost:5001/swagger` to explore the API.
-
-## Error Handling
-
-```csharp
-try
-{
- var checkout = await _ucpClient.GetCheckoutAsync("invalid-id");
-}
-catch (HttpRequestException ex) when (ex.StatusCode == System.Net.HttpStatusCode.NotFound)
-{
- Console.WriteLine("Checkout not found");
-}
-catch (HttpRequestException ex)
-{
- Console.WriteLine($"HTTP error: {ex.StatusCode} - {ex.Message}");
-}
-catch (InvalidOperationException ex)
-{
- Console.WriteLine($"Invalid operation: {ex.Message}");
-}
-catch (Exception ex)
-{
- Console.WriteLine($"Unexpected error: {ex.Message}");
-}
-```
-

-# Governance
-
-## Core Principles
-
-* Members are chosen and promoted to various committees based on their actual
- contributions.
-* Members work towards the overall health and adoption of a more open
- ecosystem and agnostic to interests of the companies they represent.
-
-## Contributors
-
-* Open - Anyone can contribute but needs to sign a contributor license.
- See [`CONTRIBUTING.md`](CONTRIBUTING.md) for details.
-* All code changes need to be approved by at least 1 maintainer elected by
- Tech Council (TC) and all TC members are cc’ed.
-
-## Maintainers
-
-* Responsible for reviewing and approving code changes to ensure they align
- with the project's technical standards and governance principles.
-* Build tools and documentation to facilitate adoption of the protocol.
-* Tech Council (TC) can add, remove & nominate maintainers as needed.
-* All code changes require approval from at least one Maintainer.
-
-### Domain Working Groups (DWG)
-
-* Because the TC cannot be experts in every field, Domain Working Groups
- (DWG) may be formed as a natural part of expanding the protocol.
-* DWG are subject to TC oversight - all DWG artifacts must be reviewed and
- approved by the TC.
-* Acts as the consensus venue for industry participants (e.g., multiple
- airlines) to agree on shared interoperability standards within the
- protocol, maintain the specific documentation and implementation guides for
- their domain's capabilities.
-* A group of 3+ organizations can submit a charter to the Governing Council
- to form a DWG (e.g., "Travel WG"). Once chartered, the DWG has autonomy to
- define capabilities for their domain and submit for TC approvals.
-
-## Tech Council (TC)
-
-* Responsible for maintaining core technical changes to the spec, e.g., adding
- new features, reviewing enhancement proposals etc.
-* Elected by the Governing Council (GC).
-* Includes 8 core members, 4 from each founding organization (Google &
- Shopify), each with 1 vote (total 8 votes).
-* Includes 4 members from any org, each with 1 vote (total 4 votes), elected
- by the TC every 6 months, based on their technical contributions towards the
- protocol. Members can be re-elected any number of times.
-* Decisions are made with a majority vote.
-* Any TC member may request a review from the Governing Council at any time
- for any additional inputs.
-
-## Governing Council (GC)
-
-* Responsible for governance, overall health and adoption of the protocol.
-* GC serves as the ultimate owner of all UCP assets. Google
- acts as the custodian of the UCP.dev domain, holding and managing it solely
- for the benefit of the Council and the partnership’s collective interests.
-* Includes a total of 2 core members, with each founding organization
- (Google & Shopify) having 1 core member, each with 1 vote (total 2 votes).
-* Includes 1 member elected annually by the GC for contributions to the
- protocol's health and adoption from any organization. For the first year,
- this seat is open, and Google holds the proxy vote for this seat, to
- facilitate rapid early stage growth & adoption of the protocol.
-* Can add/remove TC members via simple majority vote.
-* May choose to review and veto TC decision or recommendation.
-* Decisions are made with a majority vote.
-
-## Operational Rules and Process
-
-### Enhancement proposals
-
-For any significant change to the protocol, such as adding a new capability,
-altering a core construct, or changing a fundamental behavior, a written
-enhancement proposal must be submitted to the TC.
-
-An enhancement proposal is a living artifact that tracks a proposal through its
-lifecycle:
-
-* **Provisional:** The initial stage where the idea is proposed and debated
- within the community. In order to move to the next stage, the enhancement
- proposal will need to be approved by a simple majority of the TC.
-* **Implementable:** The stage after the design has been finalized and has
- received formal approval from at least one maintainer and one member of the
- TC.
-* **Implemented:** The final stage, reached when the code for the feature is
- complete, tested, documented, and merged.
-
-Every enhancement proposal must follow a standard template requiring sections
-for a Summary, Motivation, Detailed Design, Risks, a Test Plan, and Graduation
-Criteria (defining the path from Alpha to Beta to General Availability). This
-creates a permanent, public design record for the project's evolution.
-
-### Voting and decision making
-
-The path below should be followed for resolving issues that are technical in
-nature.
-
-* **L1:** routine changes (bug fixes, documentation, minor improvements) are
- auto-approved after 1 business day if no blocks are raised (silence =
- consent).
-* **L2:** For non-major version increments and standard changes, proposals are
- auto-approved after 5 business days if no objections are raised and there is
- at least one +1 from a maintainer. If objections are raised, contributors
- have 3 business days to reach a resolution.
-* **L3:** If unresolved after 5 business days, the relevant maintainer makes a
- binding decision based on technical merit and speed.
-* **L4:** Any technical issues that span across topics and cannot be resolved
- amongst maintainers and DWGs will be escalated to the TC. Significant
- changes affecting core protocol architecture must follow the Enhancement
- Proposal process, requiring TC approval before implementation.
-* **L5:** If a conflict impacts the core protocol’s scope or business
- strategy, it escalates to the Governing Council.
-
-The TC reserves the right to stop any discussions deemed non-critical to the
-protocol.
-
-### Versioning
-
-The base protocol uses date based versioning. Major version increments (breaking
-changes) require a majority Governing Council approval due to the high cost
-to the ecosystem. A quorum requires all Governing Council members (or
-appropriate representatives) to be present for decision-making. New features
-should typically be attempted through the extensions framework first. If an
-extension achieves significant usage, it can be considered for adoption into the
-next minor version of the core.
-
-## Communication
-
-To ensure the protocol remains open and agnostic, all governance activities must
-be visible, accessible, and searchable. All communication that is intended to be
-public (concerning, e.g., adding a capability before creating an extension,
-debating one approach versus another, or announcements relating to upcoming
-launches, etc.) shall take place on a shared Google group with a mailing list.
-This includes discussion on enhancement proposals, announcements about official
-specification changes and final governance votes.
-
-* **TC & DWG Meetings:** Agendas should be posted 24 hours in advance. Minutes
- and meeting notes should be published to the repository within 1 week of the
- meeting conclusion. TC reserves the right to redact or edit meeting notes as
- needed.
-* **Governing Council Meetings:** Summaries of strategic decisions and budget
- allocations will be published quarterly (specific sensitive partnership
- discussions may remain private).

-# UCP.NET - Universal Commerce Protocol for .NET
-
-[](LICENSE)
-[](https://www.nuget.org/packages/UCP.NET/)
-
-A .NET client library for [Universal Commerce Protocol (UCP)](https://ucp.dev) - enabling seamless commerce integrations with standardized APIs for checkout, payments, and order management.
-
-## Overview
-
-UCP.NET is a comprehensive .NET library that provides an easy-to-use client for integrating with UCP-compliant commerce platforms. It supports the full UCP specification including:
-
-- ✅ **Checkout Sessions** - Create and manage shopping cart checkout flows
-- ✅ **Payment Processing** - Handle payment methods and credentials securely
-- ✅ **Order Management** - Track orders from creation to fulfillment
-- ✅ **Discovery** - Automatic capability discovery from merchant endpoints
-- ✅ **Extensible** - Support for UCP extensions and custom capabilities
-
-## Installation
-
-Install the NuGet package:
-
-```bash
-dotnet add package UCP.NET
-```
-
-Or via Package Manager Console:
-
-```powershell
-Install-Package UCP.NET
-```
-
-## Quick Start
-
-### Basic Setup
-
-```csharp
-using UCP.NET.Client;
-using UCP.NET.Configuration;
-using UCP.NET.Extensions;
-
-// Configure services
-services.AddUcpShoppingClient(options =>
-{
- options.BaseUrl = "https://merchant.example.com/ucp";
- options.ApiKey = "your-api-key";
- options.ProtocolVersion = "2026-01-11";
-});
-```
-
-### Using Configuration File
-
-In `appsettings.json`:
-
-```json
-{
- "UcpClient": {
- "BaseUrl": "https://merchant.example.com/ucp",
- "ApiKey": "your-api-key",
- "ProtocolVersion": "2026-01-11",
- "TimeoutSeconds": 30
- }
-}
-```
-
-Then register the client:
-
-```csharp
-services.AddUcpShoppingClient(configuration);
-```
-
-### Creating a Checkout Session
-
-```csharp
-public class CheckoutService
-{
- private readonly IUcpShoppingClient _ucpClient;
-
- public CheckoutService(IUcpShoppingClient ucpClient)
- {
- _ucpClient = ucpClient;
- }
-
- public async Task CreateCheckoutAsync()
- {
- var request = new CheckoutCreateRequest
- {
- Ucp = new UcpMetadata
- {
- Version = "2026-01-11",
- Capabilities = new List
- {
- new Capability { Name = "checkout" }
- }
- },
- LineItems = new List
- {
- new LineItem
- {
- Id = "item-123",
- Quantity = 2,
- Item = new ItemInfo
- {
- Name = "Product Name",
- Description = "Product Description",
- ImageUrl = "https://example.com/image.jpg"
- }
- }
- }
- };
-
- var response = await _ucpClient.CreateCheckoutAsync(request);
- return response.Id;
- }
-}
-```
-
-### Updating a Checkout Session
-
-```csharp
-public async Task UpdatePaymentAsync(string checkoutId)
-{
- var updateRequest = new CheckoutUpdateRequest
- {
- Ucp = new UcpMetadata { Version = "2026-01-11" },
- Payment = new PaymentUpdate
- {
- PaymentHandler = new PaymentHandler
- {
- Id = "payment-handler-123",
- Name = "Credit Card"
- }
- }
- };
-
- var response = await _ucpClient.UpdateCheckoutAsync(checkoutId, updateRequest);
-}
-```
-
-### Completing a Checkout
-
-```csharp
-public async Task CompleteCheckoutAsync(string checkoutId)
-{
- var order = await _ucpClient.CompleteCheckoutAsync(checkoutId);
- Console.WriteLine($"Order created: {order.Id}");
- return order;
-}
-```
-
-## Clean Architecture Example
-
-Check out the complete [Clean Architecture example](examples/UCP.CleanArchitecture/) demonstrating:
-
-- **Domain Layer** - Core business entities and interfaces
-- **Application Layer** - Use cases implemented with MediatR
-- **Infrastructure Layer** - UCP client integration
-- **API Layer** - ASP.NET Core Web API
-
-### Example Structure
-
-```

-│ ├── Domain/ # Entities, Value Objects, Interfaces
-│ ├── Application/ # Use Cases, DTOs, MediatR Commands/Queries
-│ ├── Infrastructure/ # UCP Integration, Repositories
-│ └── API/ # ASP.NET Core Web API
-└── tests/
- ├── Application.Tests/
- └── Infrastructure.Tests/
-```
-
-## Features
-
-### Type-Safe Models
-
-All UCP schema types are mapped to strongly-typed C# classes with proper JSON serialization:
-
-```csharp
-public class CheckoutResponse
-{
- public required UcpMetadata Ucp { get; set; }
- public required string Id { get; set; }
- public required string State { get; set; }
- public List? LineItems { get; set; }
- public PaymentResponse? Payment { get; set; }
- public FulfillmentResponse? Fulfillment { get; set; }
- public OrderSummary? OrderSummary { get; set; }
-}
-```
-
-### Error Handling
-
-The client throws detailed exceptions for error scenarios:
-
-```csharp
-try
-{
- var checkout = await _ucpClient.GetCheckoutAsync("invalid-id");
-}
-catch (HttpRequestException ex)
-{
- // Handle HTTP errors (4xx, 5xx)
- Console.WriteLine($"HTTP Error: {ex.Message}");
-}
-catch (InvalidOperationException ex)
-{
- // Handle null responses
- Console.WriteLine($"Invalid response: {ex.Message}");
-}
-```
-
-### Dependency Injection
-
-Full support for .NET dependency injection:
-
-```csharp
-// Startup.cs or Program.cs
-builder.Services.AddUcpShoppingClient(options =>
-{
- options.BaseUrl = builder.Configuration["UcpClient:BaseUrl"]!;
- options.ApiKey = builder.Configuration["UcpClient:ApiKey"];
-});
-
-// Use in controllers
-public class CheckoutController : ControllerBase
-{
- private readonly IUcpShoppingClient _ucpClient;
-
- public CheckoutController(IUcpShoppingClient ucpClient)
- {
- _ucpClient = ucpClient;
- }
-}
-```
-
-## Configuration Options
-
-| Option | Type | Description | Default |
-|--------|------|-------------|---------|
-| `BaseUrl` | string | Base URL of the UCP endpoint | Required |
-| `ApiKey` | string | API key for authentication | null |
-| `BearerToken` | string | Bearer token for authorization | null |
-| `ProtocolVersion` | string | UCP protocol version | "2026-01-11" |
-| `TimeoutSeconds` | int | Request timeout in seconds | 30 |
-| `IncludeDetailedErrors` | bool | Include detailed error messages | true |
-| `CustomHeaders` | Dictionary | Custom headers for all requests | {} |
