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). Know before you pay.
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X POST 'https://x402.fuchss.app/v1/x402-trust' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch -X POST 'https://x402.fuchss.app/v1/x402-trust'
