Upload Assets

Import assets into the specified asset group. URL is used to pull public HTTPS resources into the asset library (review/transcoding is handled by the server). After the import succeeds, AssetId is returned. In Create Video, it is recommended to reference it as asset://{assetId} instead of repeatedly providing the public URL.

​
Method and Path

POST /v1/seedance/asset/CreateAsset
