Trust score97/100Strong

From 14 daily checks since Oct 27, 2026, last 30 days. Formula 1.0-median30.

  • Uptime, last 30 days: 100%40 / 40 pts
  • Valid x402 payment request: 100%40 / 40 pts
  • Price matches the listing: Yes10 / 10 pts
  • Median response time (up checks): 624 ms7 / 10 pts

How the score works: uptime (40 points), how often the endpoint returned a valid x402 payment request (40), whether the price in it matches the listed price (10) and median response time of the up checks (10: under 500 ms 10, 500–999 ms 7, 1–2 s 4, slower 1, 0 if the last check was not up). Parts that can’t apply are left out and the score is rescaled. Strong is 90–100, fair 70–89, weak under 70. Paying for Featured, Sponsored or any placement never changes it, and it is not an endorsement. Think it’s wrong? Email hello@youraitools.co and we’ll re-check it.

How we measure: one unpaid check per day of the listing’s example endpoint (GET https://ask.singitai.app/v1/responses). 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
