        > This `Admin API` is separate from the `Corti API` used for speech
        recognition, text generation, and agentic workflows. Authentication and
        scope for the `Admin API` uses email-and-password to obtain a bearer
        token via
        [/auth/token](/api-reference/admin/auth/authenticate-user-and-get-access-token).
        This token is only used for API administration.
