notes: >
  The Origin Trades API (Airbrush v3) authenticates with a single API key passed in the
  API-Key request header, issued by Origin. The Swagger 2.0 document models this as a
  header parameter rather than a declared securityDefinitions scheme, so the mechanical
  deriver reports no formal scheme; the auth model below is captured from the documented
  request header and the per-operation 403 "Invalid API Key" response. If the key is
  omitted the API returns the interactive documentation page instead of data.

  description: >
    Unique API key used for authentication, provided by Origin. Scopes the response to
    the trades the key has been granted access to. Invalid keys return HTTP 403 with a
    {"detail": "Invalid API Key"} body.
