Is this API safe to pay? Audit any x402 merchant or paid endpoint BEFORE you send money. Answers whether a service is trustworthy, whether it is a scam or dead, and whether it will actually deliver. Probes the live endpoint for a valid HTTP 402 challenge, detects price drift between the advertised price and the real challenge price, pulls settlement history and unique-buyer counts, and verifies on-chain USDC actually reaching the payTo address. Returns a PASS / CAUTION / AVOID verdict with the evidence behind it. Every check is measured live at request time — nothing cached, no reputation scores. Use before paying an unknown merchant, to avoid wasting money on dead or fraudulent endpoints.
