Trust score: not scored yet (fewer than 7 days of data). A score appears after at least 7 days and 6 daily checks.

How we measure: one unpaid check per day of the listing’s example endpoint (GET https://402registry.com/buy/one). We never pay and never send a payment header. Up means any answer below HTTP 500 except 404/410 within 8 seconds. Uptime counts those daily checks. Payment never changes these numbers. A technical check, not an endorsement. Raw JSON · schema
