Update an asset

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/UpdateAsset

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.
