Is this x402 endpoint safe to pay?
Is this x402 endpoint safe to pay? Reads the endpoint's own payment challenge under BOTH protocol versions — v1 body and v2 PAYMENT-REQUIRED header, so a live v2-only service is not reported as dead — extracts the payout wallet it advertises, and screens that wallet: OFAC sanctions, sybil-filtered ERC-8004 reputation, on-chain behaviour. Flags an endpoint that names different recipients under the two versions. Scores the wallet, not the service behind it, and says so.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
