Tools
| Tool | Description | Behaviour |
|---|---|---|
| attest_guard | Verify a live 402 payment offer at the moment of spend. Pass the EXACT offer you just received (url, payTo, amount, asset, network) and get an allow / warn / block verdict with machine-readable reasons: wallet mismatch vs the verified payout wallet, price swaps vs the last verified quote, danger flags, blocklisted wallets, and typosquats. Call this AFTER receiving a 402 offer and BEFORE authorizing the payment. | Not declared |
| attest_scan | Scan an agent payment endpoint (x402 / HTTP 402) and return a letter grade A to F with a safety verdict before paying. | Not declared |
