Try our paid endpoints
Run any of our paid trust products right here with a browser wallet (MetaMask, Coinbase Wallet, …). Enter the x402 endpoint URL you want to check, hit run, and approve the USDC payment — the result comes back as JSON. No code required.
Trust score
$0.005Deterministic trust score (0-100, grade A-F) with full component breakdown, flags, and 30-day on-chain USDC settlement stats for the endpoint.
Better alternatives
$0.005Top semantically-similar endpoints that out-score this one — route away from a mediocre endpoint toward a more reliable, better-settled equivalent.
Observation history
$0.020Raw discovery snapshots (listing/price/payTo changes) and probe time-series (uptime, latency, quoted amount) over your chosen window.
How it works: submitting a form sends you to the paid endpoint, which shows a wallet payment page for the amount above. After you approve the USDC payment, the same request is retried automatically with your payment attached and the JSON result is returned in your browser. You are only charged if the endpoint is in our observation set — unknown endpoints are rejected before any charge.
