Create an asset group

Availability

This page documents the Modelflare asset-management route. Calls require a valid media API key, an available media channel, and the required permission.

Note

The gateway records provider asset IDs, status, and user ownership. The Castaly local library remains separate from the provider asset namespace.

Endpoint

POST https://modelflare.dev/volc/asset/CreateAssetGroup

Authentication

Use a Modelflare API key:

bash

-H "Authorization: Bearer YOUR_MODELFLARE_API_KEY"

Send Idempotency-Key with create, update, and delete requests. Retrying the same key for the same user replays the saved response without repeating the mutation.

Request

Create a group for image, video, and audio assets used by Seedance workflows.

Field	Type	Required	Description	Example
Name	string	Yes	Name of the asset group.	my-project-assets
model	string	No	Billing model. Defaults to volc-asset.	volc-asset

JSON example:

JSON

{
  "Name": "my-project-assets",
  "model": "volc-asset"
}

cURL example:

bash

curl --request POST https://modelflare.dev/volc/asset/CreateAssetGroup \
  --header "Authorization: Bearer YOUR_MODELFLARE_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
  "Name": "my-project-assets",
  "model": "volc-asset"
}'

Response

The group was created.

Field	Type	Required	Description	Example
Id	string	Yes	The new asset group ID.	group-20260320141746-zsf6b

Response example:

JSON

{
  "Id": "group-20260320120601-hsw4s"
}

Errors

Status	Meaning
400	The request is invalid.
401	The API key is missing or unauthorized.

Error body example (when returned):

JSON

{
  "error": {
    "code": "invalid_request",
    "message": "Request validation failed."
  }
}

Image, video, and audio creation are asynchronous. After receiving an asset ID, call GetAsset and use the asset://<ID> reference only when the status is Active.
