x402 is an open, internet-native payment standard built on HTTP 402, letting clients and servers — including AI agents — pay per request with no accounts, no protocol fees, and no network lock-in.

Last 30 days: 75.41M transactions, $24.24M volume, 94K buyers, 22K sellers.

Integration is one line of paymentMiddleware: unpaid requests get an HTTP 402 response prompting the client to pay and retry, positioning x402 as infrastructure for agentic payments at scale.
