​
Authentication

Most endpoints require authentication via scoped API tokens with HMAC-SHA256 request signing:
Public endpoints like market browsing and orderbook data do not require authentication. All authenticated requests use scoped API tokens with HMAC signing (legacy static API-key headers are deprecated and no longer issued).
See the Authentication guide for HMAC signing details, or the Programmatic API guide for the full partner integration workflow.
