Wan Task Query API - Ace Data Cloud

POST https://api.acedata.cloud/wan/tasks is used to query, batch query, or delete Wan video tasks. Task queries do not incur additional generation fees.

Query a Single Task

curl -X POST 'https://api.acedata.cloud/wan/tasks' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"action":"retrieve","id":"TASK_ID"}'

The response.data.video_url of the completed task is a permanent CDN address; response.usage includes resolution, input/output video seconds, frame rate, and aspect ratio; response.cost is the settlement for the generated task.

Batch Query

{
  "action": "retrieve_batch",
  "ids": [
    "TASK_ID_1",
    "TASK_ID_2"
  ]
}

Returns { "items": [...], "count": 2 }. When tasks are in progress, there may not yet be finished_at and final response.

Delete Task Record

{
  "action": "delete",
  "id": "TASK_ID"
}

Deletion only affects task history records and will not delete the already generated CDN videos.
