About x402
The x402 payment protocol is an HTTP-based payment protocol that enables developers running resource servers to accept payments from users using a variety of payment methods. Servers declare payment requirements for specific routes. Clients send cryptographically signed payment payloads. Facilitators verify and settle payments on-chain.
Introduces support for high-frequency micropayments, real-time payment monitoring, and advanced gating capabilities. This evolution transforms x402 from a payment protocol into a comprehensive infrastructure for autonomous agent commerce.
