Comprehensive API Categories for Every Use Case
OKX organizes its API offerings into three core categories: Trading API, Data API, and Service API. Each is designed to serve specific aspects of the trading lifecycle while maintaining interoperability across systems.
Trading API: Execute with Precision
The Trading API enables users to interact directly with OKX’s matching engine, supporting a wide range of order types and trading modes.
Key features include:

Available endpoints include:
- Market Data: Access real-time ticker information, order books, trade history, and candlestick charts (klines) with customizable timeframes.
- Public Data: Retrieve instrument details, funding rates, insurance funds, and system status.
