    x-apievangelist-notes:
    - Errors are NOT RFC 9457; the envelope is {message, errors[{field, code}]}.
    - Rate limit is 5000 req/min per IP in production and 2500 in sandbox, signalled by HTTP 429 with no rate-limit
      headers.
    - No idempotency key is offered on inbound operations.
    - Access tokens from https://auth.optiturn.com/oauth/token are valid 25 hours and shared across every Optoro
      API.
