What the 402 Score measures: availability, latency, x402 spec compliance, price integrity and paid delivery - from real requests, by published rules. Scores are never self-reported and never sold.
From the operator (Mart402) - checked the seller? The other half of due diligence is verifying what it sends you (receipts, invoices, documents): the purchase-due-diligence workflow. This is a clearly labeled note from the index operator; it never affects scores or ranking.
