  version: 1.0.0
  description: 'Public v1 REST API for the bit.com exchange (a Matrixport venue): spot, USD-M and COIN-M futures, perpetuals, options, and block trades. Derived from the official bitcom-exchange SDK endpoint constants; paths, HTTP methods, operationIds and the access-key + HMAC-SHA256 auth model are authoritative. Request/response field schemas are documented at https://www.bit.com/docs and are intentionally left generic here (data payload untyped) to avoid fabrication.'
