GET https://api.annalist.dev/v1/checks/service
Use before paying an x402 service: independent checks by host or URL. Uptime and latency from repeated unpaid probes, whether the quoted price and payout wallet match the listing, real on-chain usage over 30 days with fake volume removed (self-funded payers, crawler bots, one-wallet dominance), test purchases and domain age, with a grade and reasons. Rankings are never for sale. Signed.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
