How to Make a Call

Generating a video using this model involves making two sequential API calls:

• The first one is for creating and sending a video generation task to the server (returns a generation ID).

• The second one is for requesting the generated or extended video from the server using the generation ID received from the first endpoint.

Below, you can find both corresponding API schemas.
