Grade one x402 route's Bazaar discovery metadata. Returns the diagnosis only: both x402 SDK validator verdicts, the schema-quality score, itemized defects with severities (hollow output schemas, over-500-char descriptions, wrong asset addresses, failed validation), and a 0-100 grade. Use this when you operate an x402 route and want to know exactly what is broken before paying for the repair.

From its own 402 answer at UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
