​
Call flow

  1. POST /v1/video/generations — submit task, get task_id
  2. GET /v1/video/generations/{task_id} — poll until status=completed
  3. Read the url field from the response to download the video

​
Image-to-video

Set the image field (URL or Base64) to trigger image-to-video mode. The model will animate the content of the provided image.

​
Extended parameters

For some models, metadata accepts model-specific fields such as negative_prompt, style, or quality_level. Supported fields vary by model — refer to the model’s own documentation.
