Trust score (0-100, grade A-F) for any x402 endpoint -- listed in our catalog or
Trust score (0-100, grade A-F) for any x402 endpoint -- listed in our catalog or not. Unlike uptime-only checkers, we return ECONOMIC PROOF: the REAL on-chain USDC settlement volume and distinct-payer count for the endpoint's payTo address -- is anyone actually paying it, or is it just live? Computed deterministically from continuous monitoring: 30d probe uptime, 402-envelope spec compliance, latency, observed age, on-chain settlement activity, and advertised-price stability. Includes a full component breakdown, machine-readable flags, and an honest observedDays (we report only the history we actually have, with dataCompleteSince marking our gap-free on-chain coverage). Uncataloged endpoints are live-probed on your first query and auto-adopted into the monitored catalog (first-contact score with low confidence -- history accumulates from there). Each paid call also refreshes the endpoint's free public snapshot (page, badge, card), so a fresh score shows everywhere immediately. Know before you pay.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
