# Create Material Asset Group

> Creates a Seedance virtual-avatar material group.

Create a `library_type: "aigc_avatar"` material group. Use this endpoint for virtual avatars, products, styles, and other reusable references that do not require real-person verification.

New real-person material groups are created through [visual validation](/api-reference/video/create-visual-validation-session) and cannot be created directly with this endpoint.

## Example Request

```bash theme={null}
curl https://api.aisonar.dev/v1/videos/assets/groups \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"library_type":"aigc_avatar","group_name":"Product references","description":"Reusable product shots"}'
```
