SharpCryptoExchange.Okx: A Comprehensive .NET 6 API Wrapper for OKX REST and WebSocket V5 APIs

Introduction

SharpCryptoExchange.Okx is an open-source .NET 6 API wrapper designed to interact seamlessly with the OKX cryptocurrency exchange via its REST and WebSocket V5 APIs. This library provides a robust, developer-friendly interface to access all features offered by OKX, including trading, account management, and market data retrieval.

Built upon the CryptoExchange.Net framework, this wrapper ensures high performance, reliability, and maintainability. It was forked from OKEx.Net to address rebranding (OKEx → OKX) and dependency updates, eliminating confusion for new users.

Key Features

• Full API Coverage: Supports all OKX V5 REST and WebSocket endpoints.
• Object-Oriented Design: Clear, readable objects for easy integration.
• WebSocket Efficiency: Real-time data streaming for market updates and order book depth.
• Cross-Platform: Compatible with any .NET 6+ application (Windows, Linux, macOS).

Installation

1. Clone the Repository:

   git clone https://github.com/crx-master/SharpCryptoExchange.Okx.git

2. Add Reference: Include the project in your solution and reference it in your .NET application.

Getting Started

Namespace Setup

using OkxNet;

Client Initialization

Two primary clients are available:

• OkxClient: For REST API interactions.
• OkxSocketClient: For WebSocket connections.

Example:

using var restClient = new OkxClient();
using var socketClient = new OkxSocketClient();

WebSocket API Examples

Public Feeds

Subscribe to real-time market data:

var ws = new OkxSocketClient();
var samplePairs = new List<string> { "BTC-USDT", "ETH-USDT" };

// Ticker Subscriptions
foreach (var pair in samplePairs)
{
    ws.SubscribeToTickers(pair, data => 
    {
        Console.WriteLine($"Ticker Update: {data.LastPrice}");
    });
}

// Order Book Subscription
ws.SubscribeToOrderBook("BTC-USDT", OkexOrderBookType.OrderBook, data =>
{
    Console.WriteLine($"Ask: {data.Asks[0].Price}, Bid: {data.Bids[0].Price}");
});

Private Feeds (Authentication Required)

ws.SetApiCredentials("API_KEY", "API_SECRET", "API_PASSPHRASE");

// Account Updates
ws.SubscribeToAccountUpdates(data => 
{
    Console.WriteLine($"Balance Update: {data.TotalEquity}");
});

REST API Examples

Public Endpoints

var api = new OkxClient();
var instruments = api.GetInstruments(OkexInstrumentType.Spot);
var ticker = api.GetTicker("BTC-USDT");

Authenticated Endpoints

api.SetApiCredentials("API_KEY", "API_SECRET", "API_PASSPHRASE");

// Account Balance
var balance = api.GetAccountBalance();

// Place Order
var order = api.PlaceOrder(
    instrumentId: "BTC-USDT",
    tradeMode: OkexTradeMode.Cash,
    side: OkexOrderSide.Buy,
    type: OkexOrderType.MarketOrder,
    size: 0.1m
);
