x402 Ecosystem Reliability Report · September 2026
A live, dated snapshot of how reliably x402 services answer. Every figure below is generated from the x402 List monitoring database on September 11, 2026, measured over a rolling 30-day horizon (24h / 7d / 30d windows; the API also serves a 90d window per service that fills progressively since monitoring began).
Ecosystem at a glance
As of September 11, 2026, x402 List monitors 723 services that accept x402 payments, of which 649 are payment-ready (the endpoint answers a valid x402 challenge and is live) and 14 are delivery-verified (x402 List paid a real call and the service delivered; this stronger tier starts empty and grows only with paid probes). Across the directory, average uptime is 92.6% over the rolling 30-day horizon (88.5% over 7 days, 86.2% over the latest day). On-chain settlement volume routed through tracked facilitators was $977.8k across 12,902,109 settlements in the last 30 days.
Most reliable services · 30-day uptime
10 of 432 services at 100% 30d uptime (listed A-Z, not ranked). Uptime is the share of monitoring checks that returned a valid x402 response.

Below 99% · services to watch
Services whose 30-day uptime fell below 99%. A low figure can mean a real outage, a provider in flux, or an endpoint that changed its x402 contract. Treat this as a watchlist, not a verdict.

Method & caveats
x402 List probes every listed service on a recurring schedule and records whether it returned a valid HTTP 402 payment challenge. Uptime is the share of those checks that succeeded, weighted by check count, over the stated window. This report uses the 30-day window. Raw check records are purged at 30 days, but daily uptime rollups are kept: the API also serves a 90-day window per service, which fills progressively since monitoring began. Numbers are a live snapshot taken September 11, 2026 and will drift as new checks land; the canonical, always-current view is the status page and the dated State of x402 dataset. Facilitator settlement volume is read directly on-chain.
