Most endpoints require authentication via the Partner-App-Key header. See Authentication for details.

All endpoints return a consistent error format:

{
  "error": "string",
  "error_code": "string",
  "message": "string",
  "detail": "string"
}

Successful responses are wrapped in a standard envelope:

{
  "message": "string",
  "data": { ... }
}
