## Endpoints
- POST https://moneyman-kit-x402-0sd6av.openpouch.sh/v1/probe ($0.01): body {"url":"https://..."}. Fetches the URL plus /.well-known/x402, llms.txt, skill.md and openapi.json, returns statuses, 402 terms and doc fixes.
- POST https://moneyman-kit-x402-0sd6av.openpouch.sh/v1/receipt-check ($0.005): body {"tx":"0x...","claim":"5 USDC to 0x..."}. Every USDC Transfer (logIndex), EIP-3009 AuthorizationUsed nonces, block time, verdict MATCH/PARTIAL/MISMATCH/UNPARSEABLE and binding nonce-bound/amount-only.
- POST https://moneyman-kit-x402-0sd6av.openpouch.sh/v1/x402-lint ($0.02): body {"url":"https://...","method":"GET|POST (optional)"}. Fetches the URL unpaid, decodes the 402 and checks v1/v2 shape, network, amount units, payTo, timeout, CORS expose header, and extra.name/version against the token's on-chain EIP-712 domain. Verdict PASS/WARN/FAIL. Not charged on bad input.
- POST https://moneyman-kit-x402-0sd6av.openpouch.sh/v1/auth-state ($0.005): body {"authorizer":"0x...","nonce":"0x<32 bytes>","validBefore":1700000000 (optional),"network":"eip155:8453" (optional)}. Reads USDC authorizationState: used / unused_still_valid / unused_expired, so a resumed agent knows whether re-signing a payment is safe. If used, outcome = transferred | canceled | unknown from AuthorizationUsed/AuthorizationCanceled logs (authorizationState is also true after cancelAuthorization). Optional "tx", "payTo", "amount" (atomic) give matchesExpected.
- POST https://moneyman-kit-x402-0sd6av.openpouch.sh/v1/receipt-verdict (free, 20/hour): same body, verdict and tx status only.
- GET https://moneyman-kit-x402-0sd6av.openpouch.sh/stats: public counters since last deploy.
