  format: 'Authorization: Bearer <API_KEY>'
  description: >-
    All REST API requests must include the sFOX API key in the Authorization
    header as a Bearer token. The key is a static, long-lived secret (not an
    OAuth access token). API-key permissions are inherited from the owning user
    account; permission changes apply to existing and new keys automatically.

  environments:
    production: Requires a production API key
    sandbox: Requires a separate sandbox/staging API key
  applies_to:
  - sFOX REST API (https://api.sfox.com)
  - sFOX WebSocket API (authenticate action before subscribing to private feeds)
  - sFOX Connect API
notes: >-
  WebSocket private feeds require an `authenticate` message carrying the same
  API key before subscription. Market-data endpoints such as
  GET /v1/markets/orderbook/{pair} are public and need no auth. sFOX does not use
  HMAC request signing for the REST API.
