x402 endpoint check

Validate an x402 endpoint and audit its Bazaar listing before you pay for it or list it. One unpaid probe (never pays the target) grades the 402 challenge, schemas, examples, name, tags and latency, and adds Coinbase's validator verdict, the live Bazaar listing (30-day calls, payers, stale metadata) and search rank for its own name and tags. Returns score, grade and prioritized fixes. 0.005 USDC/call; failed calls are free.
