Agent Café — the trust layer for agent payments (x402 on Base). Four services on one endpoint: CERTIFY a paying agent (public certificate + badge), SCORE any wallet's payment risk 0–100 before you transact, ESCROW your own x402 sales with automated on-chain arbitration, and the EXTERNAL ARBITER — signed delivery verdicts any escrow can execute. Real USDC, verifiable on-chain.
