  description: >-
    Access paid tools, manage prepaid balances, and build usage billing. Send
    money as exact decimal strings and reuse Idempotency-Key on retries.
    Management routes require a scoped server key or authorized dashboard
    session. Sensitive workspace changes require an owner or admin with recent
    MFA or passkey verification, except where an operation documents a stricter
    boundary. Interactive agents use MCP OAuth; unattended agents use scoped
    Agent Connections. Browser widgets use end-user tokens.
