 ## Notes on ASP.NET Core Standard Types
 
 AxisEndpoints builds directly on ASP.NET Core standard types. The types below are not AxisEndpoints-specific, so standard Minimal API knowledge applies as-is.

 This interface is provided by ASP.NET Core Minimal APIs and represents an HTTP response. It is produced by factory methods such as `Results.Json()`, `Results.Problem()`, `Results.Ok()`, and `Results.NotFound()`. In AxisEndpoints, specifying `IResult` as the return type of `HandleAsync` lets you return different response shapes based on the outcome, such as JSON on success and `ProblemDetails` on error.

+
 ### `ProblemDetails`
 
 `Microsoft.AspNetCore.Mvc.ProblemDetails` provides the standard error response format defined by RFC 9457 (formerly RFC 7807). It includes fields such as `type`, `title`, `status`, `detail`, and `errors`, which bring consistency to API error responses. AxisEndpoints' DataAnnotations validation filter also returns validation errors in this format.

 ### `IEndpointFilter`
 
 This filter interface is provided by ASP.NET Core Minimal APIs and lets you insert logic into the request pipeline. Unlike middleware, it can be scoped to specific endpoints or groups, which gives you finer control over cross-cutting concerns.
