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 theerror
field text and your best judgement to tell them apart, since themessage
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
.
