{"$schema":"https://x402-trust.com/schemas/leaderboard.schema.json","schemaVersion":"2.0.0","schemaType":"leaderboard","generatedAt":1793338985000,"dataCompleteSince":1746780801000,"methodology":"The board ranks HOSTS (providers), not individual URL paths: a host's score is the PROBE-WEIGHTED mean of the full-density scores of its listed endpoints, so a well-measured endpoint counts more than one with the bare minimum of observations, and one host cannot flood the top with many path variants. Per-endpoint score = 0.45*technical-reliability + 0.30*spec-compliance + 0.25*economic-reputation, where technical-reliability = 0.45*uptime + 0.40*observed-age + 0.15*latency (effective latency weight ≈6.75% of the final score), spec-compliance blends 402-envelope validity with x402-version support, and economic-reputation blends on-chain settlement activity, price-stability and payer-diversity; only listed, non-blocklisted endpoints with at least 3 full-density probes and a measured grade feed the mean, and the host grade is derived from the weighted mean with the same thresholds as per-endpoint grades. Full per-endpoint breakdown via paid POST /v1/x402-trust. Latency is measured from a single EU vantage point; includes network round-trip distance to the endpoint, so it is deliberately low-weighted. Templated (per-item) endpoints — whose URL carries an unresolved {param}/:param placeholder — are recognised as such: their per-item price and payTo variance is treated as dynamic-in-range (surfaced as a price range + distinct-wallet set), NOT as instability or a hijack, so they are neither price-penalised nor force-avoided for it. Settlement activity (which resolves only to the payTo wallet, not a URL path) is part of the score but not shown per-row here to avoid implying path-level volume.","coverage":{"endpointsTracked":361152,"endpointsCurrentlyListed":294495,"note":"endpointsTracked = every x402 endpoint we've ever discovered; endpointsCurrentlyListed = those still present in upstream discovery (not delisted).
