This endpoint allows you to download assets from your paid Kling account without watermarks by providing the work IDs.

https://api.useapi.net/v1/kling/assets/download?…

Request Headers 
Authorization: Bearer {API token}
Query Parameters

  • email is optional when only one account configured.
    However, if you have multiple accounts configured, this parameter becomes required.

  • workIds is required, specify the IDs of works to download.
    Can be a single numeric string or a comma-separated list of numeric strings (e.g., “123456789” or “123456789,987654321”).
    These IDs can be obtained from the workId field in the works array returned by the GET /assets, GET /tasks or GET /tasks/task_id endpoint.

  • fileTypes is optional, specify comma-separated file types you want to download (e.g., “MP4” or “MP4,WAV”). If not provided, all available files for the given workIds will be downloaded as a singe .zip file.
    Supported file types: MP4, MP3, WAV, PNG.

Note: If a single workId is provided with a single fileTypes value, the cdnUrl will point to an actual asset file. If multiple workIds are provided or fileTypes is omitted or has multiple values, the cdnUrl will point to a .zip file containing all requested assets/files.
