Listed but never paid? One call answers why. We run a real paid test purchase against your x402 endpoint (not a lint) and name the exact fault when the flow breaks — 402-again loops, invalid_payload, malformed accepts. Then the half no linter has: your category's actual on-chain demand — who earns, the median price paid, your price against it. Signed, recomputable verdict from the trust hub that indexes every Bazaar seller's payment history. agenteconomy.cloud (mcp-pricing-v1.1)
