Approval Relay

Human approval for unattended AI agents: when an agent needs a person to approve an irreversible action (delete, send, deploy, spend), it gets a one-time approve link to pass to its human, waits for approve/deny, and receives an Ed25519-signed decision receipt. 0.02 USDC per request (x402, Base); 3 free per day.
