TollWarden
https://tollwarden.comCall this before your agent settles any x402 payment to check it for fraud. TollWarden answers 'is this payment safe to send?' and 'is this 402 offer safe to pay?' — catching payments to attacker-controlled addresses injected into content the agent just read (prompt-injection-triggered payments), replayed authorizations, overpayment vs the quote, secrets leaking through payment metadata, fake/lookalike USDC contracts, and address poisoning. Returns allow/flag/block with machine-readable reasons and an Ed25519-signed verdict a wallet can enforce. Non-custodial: never holds keys or funds; wraps whatever wallet/facilitator the agent already uses.

How often it was reachable when we probed it (weight 35%).
How quickly it answers when it is up — fast scores high (weight 20%).
Whether it serves over working TLS / https (weight 15%).
Whether the operator disclosed what it does — description, schema, identity (weight 15%).
Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).
Confidence 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.
