Short evidence fragment

Track usage of server-side tools such as web search.

Researcher’s reading note

The Console Admin API supports historical token/cost reporting with model, workspace and API-key dimensions, including cache categories and server tools. Enterprise SaaS reporting uses a different API.

Limits and use

Provider reports need application metadata to map costs to accepted business outcomes; permissions and product coverage differ.
