Comprehensive Cryptocurrency Exchange API for Trading & Market Data

Overview

OKEx API provides REST, WebSocket, and FIX protocol support for seamless integration with its global cryptocurrency exchange. It delivers JSON-formatted responses (and FIX for institutional users) across endpoints for real-time market data (order books, tickers, trades), trading operations (order placement/cancellation), account management (balances, transaction history), and margin/futures trading. Ideal for building automated trading bots, portfolio trackers, market analysis tools, or integrating exchange functionality into apps. Supports hundreds of cryptocurrencies and trading pairs, with scalable access for retail and institutional developers.
