XT.Net is a client library for accessing the XT 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 client based on the CryptoExchange.Net base library
• Native AOT support

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.

dotnet add package XT.Net

XT.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 XTRestClient();
var tickerResult = await restClient.SpotApi.ExchangeData.GetTickersAsync("eth_usdt");
var lastPrice = tickerResult.Data.Single().LastPrice;

Place order:

var restClient = new XTRestClient(opts => {
	opts.ApiCredentials = new XTCredentials("APIKEY", "APISECRET");
});

// Place Limit order to go long 0.1 for ETH at 2000
var orderResult = await restClient.UsdtFuturesApi.Trading.PlaceOrderAsync(
    "ETH_USDT",
    OrderSide.Buy,
    OrderType.Limit,
    0.1m,
    PositionSide.Long,
    2000
    );

WebSocket subscription:

// Subscribe to ETH/USDT ticker updates via the websocket API
var socketClient = new XTSocketClient();
var tickerSubscriptionResult = socketClient.SpotApi.SubscribeToTickerUpdatesAsync("eth_usdt", (update) => 
{
  var lastPrice = update.Data.LastPrice;
});

For information on the clients, dependency injection, response processing and more see the documentation, or have a look at the examples here or here.

XT.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 allows for easy access to different exchange API's.

When using multiple of these API's the CryptoClients.Net package can be used instead 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.
