Errors

Only the errors this operation can return. Every error uses the same envelope.

Status	Code	Meaning
400	`bad_request`	The request is malformed or fails validation.
404	`not_found`	The requested resource does not exist or is outside the caller's scope.

Every call can also return unauthorized (401), rate_limit_exceeded (429) or internal_error (500 / 502). See Responses and errors.
