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.

Income is all USDC received by the provider's payout address on Base, whatever the source. Score: 0-100: 50 x share of checks in the last 72 h that returned valid x402 payment terms + 30 x min(1, log10(1 + USDC received in 7 days) / 4) + 20 x min(1, log10(1 + distinct payers in 7 days) / 3). A provider never checked scores on income only; income is all USDC received by its payout address on Base, whatever the source. JSON: /v1/observatory/providers/list-smith-production.up.railway.app
