Uploads a Seedance material asset into a TokenLab material group. Upload a publicly reachable material URL into the selected Seedance 2.0 material library. The asset is scoped to the authenticated organization. For most requests, set library_type and omit group_id; TokenLab will use or create the organization default group for that library type. Pass group_id only when you need to upload into a specific material group.
  • aigc_avatar: virtual-person or avatar materials.
  • liveness_face: certified real-person materials.
After creation, poll Get Material Asset until status is ACTIVE. Then pass the returned id as material_asset_id, or include it in material_asset_ids, when calling Create Video. If the asset becomes FAILED, inspect error_message, fix the source material, and create a new asset.
