Bitfinex.Net

Bitfinex.Net is a strongly typed client library for accessing the Bitfinex REST and Websocket API. All data is mapped to readable models and enum values. Additional features include an implementation for maintaining a client side order book, easy integration with other exchange client libraries and more.

Supported Frameworks

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

.NET implementation	Version Support
.NET Core	`2.0` and higher
.NET Framework	`4.6.1` and higher
Mono	`5.4` and higher
Xamarin.iOS	`10.14` and higher
Xamarin.Android	`8.0` and higher
UWP	`10.0.16299` and higher
Unity	`2018.1` and higher

Get the library

dotnet add package Bitfinex.Net

How to use

REST Endpoints

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

Websocket streams

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

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

CryptoExchange.Net

Bitfinex.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.

Exchange	Repository	Nuget
Binance	JKorf/Binance.Net
BingX	JKorf/BingX.Net
Bitget	JKorf/Bitget.Net
Bybit	JKorf/Bybit.Net
CoinEx	JKorf/CoinEx.Net
