What the listing says

Use before paying an x402 endpoint you have not used before, when you cannot tell a working seller from a trap, a testnet address dressed as mainnet, or a listing whose price no longer matches its challenge. Returns a verdict — live, degraded, trap, testnet or dead — a 0-100 risk score, and the specific findings behind both, so an agent can decline a bad endpoint instead of learning about it by losing the money. Costs less than the smallest payment it protects.
