The NuGet package files are added along side the source with the latest GitHub release which can found here.

How to use

• REST Endpoints

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

• Websocket streams

    // Subscribe to ETH/USDT ticker updates via the websocket API
    var socketClient = new AsterSocketClient();
    var tickerSubscriptionResult = socketClient.SpotApi.SubscribeToTickerUpdatesAsync("ETHUSDT", (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.

CryptoExchange.Net

Aster.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.
