Examples

​
Example 1: Batch submit (auto-create group)

When group_id is not provided, the server automatically creates an AIGC asset group before submitting. 
{
  "group": {
    "name": "virtual-avatar-group",
    "description": "demo group"
  },
  "project_name": "default",
  "asset_type": "Image",
  "assets": [
    {
      "url": "https://example.com/avatar-a.png",
      "name": "avatar-a"
    },
    {
      "url": "https://example.com/avatar-b.png",
      "name": "avatar-b"
    }
  ]
}

​
Example 2: Append assets to an existing group

Provide group_id to skip group creation and submit directly. 
{
  "group_id": "group_xxx",
  "project_name": "default",
  "asset_type": "Image",
  "assets": [
    {
      "url": "https://example.com/avatar-a.png",
      "name": "avatar-a"
    }
  ]
}

​
Example 3: Single-asset shorthand

For a single asset, use the top-level url and name fields directly. 
{
  "group_id": "group_xxx",
  "url": "https://example.com/avatar.png",
  "asset_type": "Image",
  "name": "avatar-1"
}

​
Query Review Result

Asset submission is an asynchronous task. Use the Get Task Status endpoint to poll: 
GET /v1/tasks/{id}

​
Partial Failure

If any asset fails review, the task status becomes failed. Successfully approved assets remain usable and appear in result.usable_assets.

  "code": 200,
  "data": {
    "id": "task_01K...",
    "status": "failed",

        {
          "asset_id": "asset_b",
          "asset_url": "asset://asset_b",

        }
      ],
      "usable_assets": [

        }
      ],
      "failed_assets": [
        {
          "asset_id": "asset_b",
          "asset_url": "asset://asset_b",
          "status": "Failed"
        }
      ]
    },
    "error": {
      "code": "task_failed",
      "message": "Some assets failed review"
    }
  }
}
  • result.usable_assets[].asset_url can be used directly in Seedance 2.0 video generation
  • Assets in result.failed_assets must be replaced or resubmitted
  • Single-asset tasks also return result.asset_url for compatibility

​
Using Approved Assets

Pass the asset://... URL directly to the Seedance 2.0 Video Generation endpoint: 
{
  "model": "doubao-seedance-2.0",
  "prompt": "The character walks naturally along a city street",
  "image_urls": ["asset://asset_a"],
  "duration": 5,
  "resolution": "720p"
}
Once the server detects the asset:// prefix, it submits the generation task directly without triggering another asset review.
