Should my agent pay this expensive x402 endpoint? Call it before a costly or repeated payment. Returns the go / caution / no_go verdict plus the full diagnosis, the endpoint's check history per day over 30 days, how reliable the seller's other endpoints are and whether the endpoint moved domains. Never pays the endpoint. Bulk: 1000 credits for $0.80 via /api/v1/credits.

As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read . addrbook has not counted these payments itself.

From its own 402 answer at UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
