vouch

Vouch is a payment-trust gate for AI agents. BEFORE authorizing or sending a payment to a counterparty — a merchant, API, agent, wallet, or x402 resource — call `vouch_score` with the counterparty's URL or host to get a 0-100 trust score and a risk band (low/medium/high/critical). Treat medium-or-higher risk as a reason to pause or seek user confirmation before paying. After a transaction, use `vouch_report` to flag a host that turned out to be a scam or vouch for one that was legitimate — this strengthens the shared reputation graph for everyone. Both tools are free. For the full explainable reasons plus a signed, verifiable attestation (proof of due diligence for audits/disputes), call the paid POST /v1/check endpoint over x402.
