Turn a verified-but-not-settled x402 payment attempt into an executable recovery pack: verify-to-settle diagnosis, facilitator failover plan, same-request replay policy, settlement evidence checklist, receipt fallback policy, buyer stop conditions, seller patch actions, copy-paste recovery JSON, curl replay template, and first-payment-client recovery command. Built for the real quote/payment/header/verify/settle gap where buyers are closest to paying but fail before receipt evidence. This deterministic endpoint does not call an upstream model and never asks for private keys. Pay $0.012 per request with x402 exact USDC on Base or Solana when advertised.
