Full audit of your x402 API in one call, with a prioritized fix list
Full audit of your x402 API in one call, with a prioritized fix list. Lints /openapi.json, /.well-known/x402 and every paid route's 402, checks up to 10 routes in depth (payable EIP-712 domain, resource URL, CDP validate, Bazaar listing, payers, search rank vs competitors' prices), adds our 30-day uptime, and makes one real purchase to prove payment, settlement and the answer work (Base Sepolia if accepted, else Base up to $0.05, paid by us).
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.
