Install the library

NuGet

dotnet add package BloFin.Net

GitHub packages

BloFin.Net is available on GitHub packages. You'll need to add https://nuget.pkg.github.com/JKorf/index.json as a NuGet package source.

Download release

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

API key

For accessing authenticated endpoints an API key is required. When creating an API key in the BloFin web interface select Connect to Third-Party Application and select JKorf as the application name. BloFin requires users to select the application they're using with the API key. Selecting a different application will not work with the library.

How to use

• REST Endpoints

   // Get the ETH/USDT ticker via rest request
   var restClient = new BloFinRestClient();
   var tickerResult = await restClient.FuturesApi.ExchangeData.GetTickersAsync("ETH-USDT");
   var lastPrice = tickerResult.Data.FirstOrDefault()?.LastPrice;

• Websocket streams

   // Subscribe to ETH/USDT ticker updates via the websocket API
   var socketClient = new BloFinSocketClient();
   var tickerSubscriptionResult = socketClient.FuturesApi.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.

CryptoExchange.Net

BloFin.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 which combines this and the other packages and allows easy access to all exchange API's.
