CoinEx.Net

CoinEx.Net is a strongly typed client library for accessing the CoinEx 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
• Cient 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

Discord

A Discord server is available here. Feel free to join for discussion and/or questions around the CryptoExchange.Net and implementation libraries.

Getting Started

The package is available on Nuget. After installing the package the CoinEx API is available by using the CoinExRestClient and CoinExSocketClient.

Installation

Nuget

dotnet add package CoinEx.Net

GitHub packages

CoinEx.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 Access

CoinEx.Net can be configured using Dotnet dependency injection, after which the clients can be injected into your services. It also correctly configures logging and HttpClient usage.

// Configure options from config file
// see https://github.com/JKorf/CryptoExchange.Net/tree/master/Examples/example-config.json for an example
builder.Services.AddCoinEx(builder.Configuration.GetSection("CoinEx"));
		  
// OR
		  
 builder.Services.AddCoinEx(options => {
  // Configure options in code
  options.ApiCredentials = new ApiCredentials("APIKEY", "APISECRET");
});

The ICoinExRestClient and ICoinExSocketClient can then be injected.

Alternatively the rest and socket client can be constructed directly

var restClient = new CoinExRestClient(options => {
  // Options can be configured here, for example:
  options.ApiCredentials = new ApiCredentials("APIKEY", "APISECRET");
});
var socketClient = new CoinExSocketClient();
