Open HTTP-native payment standard from Coinbase for internet-native payments and AI agent transactions.
x402 is an open, neutral standard for internet-native payments that enables clients and servers to transact directly over HTTP. A server can require payment for an endpoint by responding with HTTP 402, prompting an AI agent or client to pay and retry.
The protocol supports multiple networks and payment schemes, with a focus on stablecoins and low-friction onboarding. It is designed for agentic payments at scale, removing the need for accounts, API keys, or prepaid credits.
