}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-i2v (image-to-video): give a first frame + prompt to bring the image to life, and optionally pass driving_audio to make the portrait follow the audio’s mouth movements and rhythm. For the full async flow, see the Wan Overview.- Audio drive is exclusive to
wan2.7-i2v: HappyHorse i2v does not supportdriving_audio, so lip-sync / rap must usewan2.7-i2v. input.mediais required, otherwise the upstream returnsimage-to-video model ... must provide an image. Each mediaurlmust be a public https link that can be fetched directly with GET.- Creation requests go to
/wan/api/v1/...withX-DashScope-Async: enable; do not use/v1/videos.

Check status and download
Once you have thetask_id, follow these three steps to poll status and download the mp4:
- Poll
GET /v1/tasks/{task_id}(withAuthorization; the query does not need theX-DashScope-Asyncheader), every 5-10 seconds (not < 3 seconds), untilstatusbecomescompleted. - Status values:
submitted(queued) /in_progress(generating;progressoften sitting at 30% is normal) /completed(success) /failed(checkerror). - Download: GET the
result_urlfrom the response directly, without theAuthorizationheader (it is an OSS signed direct link — sending Auth returns 403);result_urlexpires in 24 hours by default, so save it promptly.
curl "https://api.apiyi.com/v1/tasks/f8ca39a0-6f4b-4ec2-99bf-8b9649d946c4" \
-H "Authorization: Bearer sk-your-api-key"
{
"status": "completed",
"progress": 100,
"result_url": "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=...",
"task_id": "f8ca39a0-6f4b-4ec2-99bf-8b9649d946c4"
}
# result_url is an OSS signed direct link — do NOT send the Authorization header (it returns 403)
curl -L -o out.mp4 "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=..."
TASK_ID="f8ca39a0-6f4b-4ec2-99bf-8b9649d946c4"
URL=$(curl -s "https://api.apiyi.com/v1/tasks/$TASK_ID" \
-H "Authorization: Bearer sk-your-api-key" | jq -r '.result_url')
curl -L -o out.mp4 "$URL" # no Authorization
The above is the quick check/download path for “already have a task_id”. For the full polling loop (with timeout fallback) and Python client, see Wan Overview · Async call flow.
