Errors - Kloo API

The API uses conventional HTTP status codes. Errors return a JSON body with an errors array:

{
  "errors": [
    {
      "title": "You do not have access to the API.",
      "status": 401
    }
  ]
}

404	The requested resource was not found
429	Too many requests — rate limit exceeded
