x402 Protocol Service Directory

State of x402 - directory statistics

x402 is an open protocol built on the HTTP 402 Payment Required status code that lets AI agents pay for APIs in stablecoins on-chain, with no accounts or API keys. This page reports the live state of the x402 ecosystem as tracked by x402 List, on a rolling 30-day horizon.

As of August 13, 2026, 534 services are listed as accepting x402 (444 answering now, 90 offline, 8 for 30 days or more), 464 payment-ready and 0 delivery-verified, average uptime 92.4% (rolling 30d).

Every figure below is generated live from the x402 List monitoring database on August 13, 2026. Uptime is measured in rolling 24h / 7d / 30d windows here; the API also serves a 90d window per service that fills progressively since monitoring began. Facilitator volume is read directly on-chain. Payment-ready counts services whose endpoint answers a valid x402 challenge and is live (a discovery signal, not an endorsement); verified counts the stronger tier, where x402 List paid a real call and the service delivered. The verified tier starts empty and grows only with paid probes, so it can read 0 while the directory is very much alive. See methodology.
