How to Make a Call
Step-by-Step Instructions
Generating a video using this model involves sequentially calling two endpoints:
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 video from the server using the generation ID received from the first endpoint.
Below, you can find both corresponding API schemas.
API Schemas
Create a video generation task and send it to the server
You can generate a video using this API. In the basic setup, you only need a prompt.
This endpoint creates and sends a video generation task to the server â and returns a generation ID.
post
Body
modelstring ¡ enumRequiredPossible values:
promptstringRequired
The text description of the scene, subject, or action to generate in the video.
video_urlstring ¡ uriRequired
A HTTPS URL pointing to a video or a data URI containing a video. This video will be used as a reference during generation.
strengthnumber ¡ max: 1Optional
Denoising strength for the video-to-video generation. 0.0 preserves the original, 1.0 completely remakes the video.
Default: 0.85
enable_prompt_expansionbooleanOptional
Whether to enable prompt expansion.
Default: true
seedintegerOptional
Varying the seed integer is a way to get different results for the same other request parameters. Using the same value for an identical request will produce similar results. If unspecified, a random number is chosen.

Retrieve the generated video from the server
After sending a request for video generation, this task is added to the queue. This endpoint lets you check the status of a video generation task using its id, obtained from the endpoint described above.
If the video generation task status is completed, the response will include the final result â with the generated video URL and additional metadata.

Full Example: Generating and Retrieving the Video From the Server
The code below creates a video generation task, then automatically polls the server every 10 seconds until it finally receives the video URL.
