AI agents shouldn't borrow user accounts or share API keys. In AuthPI, agents are first-class identities
(agt_) with their own credentials, scopes, organization memberships, and audit trail. Secret verifiers mint
short-lived OAuth tokens through the standard client_credentials grant; wallet verifiers bind x402-paying
crypto wallets (CAIP-2) to a stable agent identity; suspending an agent cuts its access within one five-minute token TTL.
