  80. 95x402-trust.com/v1/x402-trustTrust 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.$0.005 Base956 ms4 payers100% up
