Bitfinex.Net is a strongly typed client library for accessing the Bitfinex REST and Websocket API.
- 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 order book implementation
- Extensive logging
- Support for different environments
- Easy integration with other exchange client based on the CryptoExchange.Net base library
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 |

dotnet add package Bitfinex.Net
Bitfinex.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.
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.
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.
