> Use a user-bound `ca_` bearer credential with the stated account scope, or an application session. Workspace `ck_` keys and their OAuth tokens do not grant account authority.

    Scoped agent chat, account credential lifecycle and workspace bootstrap
    operations.
  description: >-
    Canonical external schema for implemented REST operations. Account
    credentials and application sessions authorize the documented account and
    workspace operations separately from workspace keys. Exchange a workspace
    API-key client ID and secret for a short-lived OAuth access token, or use
    the `ck_` key directly for backward compatibility. `requestId` is optional
    but, when supplied, becomes the idempotency key for retries of the same chat
    input.
