.HTX.Net HTX.Net

.NET License

HTX.Net, previously known as Huobi.Net, is a strongly typed client library for accessing the HTX REST and Websocket API.

Features

  • Response data is mapped to descriptive models
  • Input parameters and response values are mapped to discriptive enum values where possible
  • Automatic websocket (re)connection management
  • Client side rate limiting
  • Client side order book implementation
  • Extensive logging
  • Support for different environments
  • Easy integration with other exchange client based on the CryptoExchange.Net base library

Supported Frameworks

The library is targeting both .NET Standard 2.0 and .NET Standard 2.1 for optimal compatibility

How to use

REST Endpoints

// Get the ETH/USDT ticker via rest request
var restClient = new HTXRestClient();
var tickerResult = await restClient.SpotApi.ExchangeData.GetTickerAsync("ETHUSDT");
var lastPrice = tickerResult.Data.ClosePrice;

Websocket streams

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

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

CryptoExchange.Net

HTX.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.
