OKX.Net

OKX.Net is strongly typed client library for accessing the OKX 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

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 packge is available on Nuget. After installing the package the OKX API is available by using the OKXRestClient and OKXSocketClient.

Installation

Add the package via dotnet, or add it via the package manager.

dotnet add package JK.OKX.Net

API Access

OKX.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.

builder.Services.AddOKX(options => {
  // Options can be configured here, for example:
  options.ApiCredentials = new ApiCredentials("APIKEY", "APISECRET");
});

The IOKXRestClient and IOKXSocketClient can then be injected.

Alternatively the rest and socket client can be constructed directly

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