  description: >-
    Public account and disposable Android session API. Open beta. Create
    responses are asynchronous; session duration includes provisioning, while
    billing begins at readiness. This specification documents the current
    supported client contract, not internal management interfaces. All example
    IDs, links, timestamps, limits, prices and digests are illustrative, not
    live credentials, measurements, or account entitlements.
