429 responses

When quota or rate limits are exceeded, YALG returns 429 Too Many Requests. Use the Retry-After header when present before retrying. 
{
  "statusCode": 429,
  "message": "Rate limit exceeded",
  "error": "Too Many Requests"
}

Retry guidance

  • Retry 429 responses after Retry-After.
  • Use exponential backoff for transient 5xx responses.
  • Do not retry validation errors until the payload is fixed.
  • Avoid high-frequency polling when job status can be checked at a slower cadence.
