400 Bad Request

{
  "error": "At least two images must be provided"
}

401 Unauthorized

{
  "error": "Unauthorized",
  "code": 401
}

404 Not Found

Kling was unable to locate one of the referenced assets. Make sure to use POST /assets to upload assets.

{
    "error": "Sorry, the requested resource was not found (VALID.ResourceNotFound)",
    "message": "Not Found"
}

500 Internal Server Error

Kling uses a 500 response to indicate moderation and other issues with the input. It may be hard to separate actual 500 errors from moderation errors, so use the error field text and your best judgement to tell them apart, since the message field most often has very generic and perhaps misleading text.
```
{
  "error": "The content you uploaded appears to violate the community guidelines. (CM_EXT.POther)",
  "message": "Service busy (CM_EXT.POther)"
}
```

When successful, the response includes a task ID which can be used to check the status using GET /tasks/task_id.
