Kling Text-to-Video

Kling's official API-compatible format, generating video from a text description; supported models include kling-v1, kling-v1-5, etc. See also Kling Image-to-Video and Get text-to-video task status.

Different path prefix

The Kling format uses the /kling/... path prefix — without the /v1 prefix used elsewhere in this documentation. Authentication is still Authorization: Bearer <YOUR_API_KEY>.
