Pionex.Net is a client library for accessing the Pionex REST and Websocket API.
- Response data is mapped to descriptive models
- Input parameters and response values are mapped to discriptive enum values where possible
- High performance
- Automatic websocket (re)connection management
- Client side rate limiting
- Client side order book implementation
- Support for managing different accounts
- Extensive logging
- Support for different environments
- Easy integration with other exchange clients based on the CryptoExchange.Net base library
- Native AOT support
The Pionex.Net documentation is the main resource for installing, configuring, and using the library.

The library is targeting both .NET Standard 2.0 and .NET Standard 2.1 for optimal compatibility, as well as the latest dotnet versions to use the latest framework features.
| .NET implementation | Version Support |
|---|---|
| .NET Core | 2.0 and higher |
| .NET Framework | 4.6.1 and higher |
| Mono | 5.4 and higher |

| UWP | 10.0.16299 and higher |
| Unity | 2018.1 and higher |
dotnet add package Pionex.Net
Pionex.Net is available on GitHub packages. You'll need to add https://nuget.pkg.github.com/JKorf/index.json as a NuGet package source.
The NuGet package files are added along side the source with the latest GitHub release which can found here.
Basic request:
// Get the ETH/USDT ticker via rest request
var restClient = new PionexRestClient();
var tickerResult = await restClient.SpotApi.ExchangeData.GetTickersAsync("ETH_USDT");
var lastPrice = tickerResult.Data.Single().ClosePrice;Place order:
var restClient = new PionexRestClient(opts => {
opts.ApiCredentials = new PionexCredentials("APIKEY", "APISECRET");
});
// Place Limit order to buy 0.1 ETH at 2000
var orderResult = await restClient.SpotApi.Trading.PlaceOrderAsync(
"ETH_USDT",
OrderSide.Buy,
OrderType.Limit,
0.1m,
price: 2000
);WebSocket subscription:
// Subscribe to ETH/USDT ticker updates via the websocket API
var socketClient = new PionexSocketClient();
var tickerSubscriptionResult = socketClient.SpotApi.SubscribeToTradeUpdatesAsync("ETH_USDT", (update) =>
{
var tradePrice = update.Data.First().Price;
});For more examples and explanations, continue with the Pionex.Net documentation or browse the compilable repository examples.

The CryptoExchange.Net Shared APIs provide exchange-agnostic, unified interfaces for common operations such as retrieving tickers, order books and balances, placing orders, and subscribing to market updates.
This allows the same application code to work with different exchange libraries. The supported Pionex API surfaces expose their shared functionality through a SharedClient property. Because support differs between exchanges and API surfaces, call Discover() to inspect the available trading modes, environments, endpoints, and subscriptions at runtime.
| API | Type | Supported interfaces |
|---|---|---|
SpotApi |
REST | IBalanceRestClient, IBookTickerRestClient, IKlineRestClient, IOrderBookRestClient, IRecentTradeRestClient, ISpotOrderRestClient, ISpotSymbolRestClient, ISpotTickerRestClient |
SpotApi |
WebSocket | IBalanceSocketClient, IBookTickerSocketClient, IOrderBookSocketClient, ISpotOrderSocketClient, ITradeSocketClient, IUserTradeSocketClient |
var sharedClient = new PionexRestClient().SpotApi.SharedClient;
var clientInfo = sharedClient.Discover();
Console.WriteLine(clientInfo);using Pionex.Net.Clients;
using CryptoExchange.Net.SharedApis;
var sharedClient = new PionexRestClient().SpotApi.SharedClient;
ISpotTickerRestClient tickerClient = sharedClient;
var symbol = new SharedSymbol(TradingMode.Spot, "ETH", "USDT");
var result = await tickerClient.GetSpotTickerAsync(
new GetTickerRequest(symbol));
if (!result.Success)
{
Console.WriteLine(result.Error);
return;
}
Console.WriteLine(result.Data.LastPrice);The request and response models belong to CryptoExchange.Net.SharedApis, so the same pattern can be used with another exchange's SharedClient.
Pionex.Net is based on the CryptoExchange.Net base library. Other exchange API implementations based on the CryptoExchange.Net base library are available and follow the same logic.
CryptoExchange.Net also provides shared access to different exchange APIs.

When using multiple of these API's the CryptoClients.Net package can be used which combines this and the other packages and allows easy access to all exchange API's.
A Discord server is available here. For discussion and/or questions around the CryptoExchange.Net and implementation libraries, feel free to join.
