⚪attest_scan(url)
Scan an agent payment endpoint (x402 / HTTP 402) and return a letter grade A to F with a safety verdict before paying.

"type": "object",
"properties": {
"url": {
"type": "string",
"description": "The endpoint URL to scan."

"required": [

}🟢attest_guard(url, payTo, amount, asset, network, ...)
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.
