Use this file to discover all available pages before exploring further.

The Playground on the right lets you debug directly: put Bearer sk-your-api-key in Authorization, fill in model / input.media / parameters, and send the request. A successful submission returns a task_id; see below for polling and download.
This page is the creation endpoint for wan2.7-videoedit (video edit): give a video + 1-5 reference images + a natural-language edit instruction to edit video elements, such as swapping outfits or backgrounds. Note the model name has no hyphen (videoedit). For the full async flow, see the Wan Overview.
  • input.media must contain both a video (the video being edited) and at least one reference_image (the reference asset, ≤5).
  • The model name is wan2.7-videoedit (no hyphen), different from HappyHorse’s happyhorse-1.0-video-edit (with hyphens), so don’t mix them up.
  • Creation requests go to /wan/api/v1/... with X-DashScope-Async: enable; do not use /v1/videos.

The video edit output duration follows the input video, not the duration parameter, so this capability usually does not pass duration.
