}

The Playground on the right lets you debug directly: put Bearer sk-your-api-key in Authorization, fill in model / input / 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-t2v (text-to-video). It needs only a text prompt, no media. To make an image move or preserve subject features, use Image-to-Video / Reference-to-Video instead. For the full async flow, status table, and Python client, see the Wan Overview.

• Creation requests must go to /wan/api/v1/services/aigc/video-generation/video-synthesis with the header X-DashScope-Async: enable. Do not use /v1/videos.
• duration must be an integer (5, not "5"); write resolution in uppercase (720P).

Response format

A successful creation returns a task_id (not the video itself):

{
  "output": { "task_id": "c2e7570c-0af2-4eba-919f-3af3d1164a38", "task_status": "PENDING" },
  "request_id": "a23b81b0-0c05-9972-a6c9-ee757400afdb"
}

Check status and download

Once you have the task_id, follow these three steps to poll status and download the mp4:

• Poll GET /v1/tasks/{task_id} (with Authorization; the query does not need the X-DashScope-Async header), every 5-10 seconds (not < 3 seconds), until status becomes completed.
• Status values: submitted (queued) / in_progress (generating; progress often sitting at 30% is normal) / completed (success) / failed (check error).
• Download: GET the result_url from the response directly, without the Authorization header (it is an OSS signed direct link — sending Auth returns 403); result_url expires in 24 hours by default, so save it promptly.

Check status

curl "https://api.apiyi.com/v1/tasks/c2e7570c-0af2-4eba-919f-3af3d1164a38" \
  -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": "c2e7570c-0af2-4eba-919f-3af3d1164a38"
}

# 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="c2e7570c-0af2-4eba-919f-3af3d1164a38"
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.
