About this API

OKX (formerly OKEx) was founded 2017 by Star Xu (Chinese background), rebranded to OKX in 2022 for internationalization. Typically ranks in top 5 exchanges globally. Differentiated by "unified account" — OKX launched unified trading account design before Binance (spot, perpetuals, options in one account, cross-product margin), combined with its Web3 wallet integration (one wallet manages both CEX balance and on-chain DeFi assets) — advanced experience for high-end users. API is feature-rich (v5 is current main version), complete SDKs. Slightly smaller than Binance/Bybit but functionally not weaker.
