OKX
OKEx rebranded to OKX in 2022 and its old okex.com/docs/ portal is gone entirely; the live API reference now lives at okx.com/docs-v5. The v5 REST and WebSocket API covers spot, margin, futures, options, and perpetual swaps, authenticated via an API key, secret, and passphrase with HMAC-SHA256-signed requests, and access is free with VIP fee tiers tied to trading volume rather than data pricing.
