What is the Kling API?

Kling API gives developers access to Kuaishou's Kling video-generation models through PiAPI for text-to-video and image-to-video workflows.

Which Kling versions can I use?

The Kling API playground supports Kling 1.6, 2.5, 2.6, and 3.0. Available modes, durations, and native-audio options depend on the version you select.

How do I call the Kling API?

Create an API key, submit a video_generation task to the PiAPI task endpoint, and poll the returned task ID until the result is complete.

Can I use an image as input?

Yes. Kling supports both text-to-video and image-to-video generation; add an image URL to the task input for an image-guided clip.
