x402

x402 is an autonomous payment protocol that supports AI, websites, and applications to automatically send and receive payments, provides programmable settlement and multi-chain compatibility, and is committed to building automated decentralized payment solutions.

What is x402?

x402 is an open payment standard that enables AI agents and APIs to perform real-time, pay-as-you-go transactions using cryptocurrencies, including stablecoins like USDC. By leveraging the HTTP 402 'Payment Required' status code, x402 facilitates seamless, autonomous payments without the need for pre-funded accounts or API keys.

How Does x402 Work?

x402 integrates with existing web protocols to allow AI agents and APIs to autonomously pay per use. When an AI agent requests access to a paid resource, the server responds with a 402 status code, providing payment instructions. The agent then executes the payment on-chain, and upon confirmation, the server grants access to the resource. This process occurs in milliseconds, enabling frictionless transactions.

What Makes x402 Unique?

x402 stands out by activating the previously unused HTTP 402 status code to facilitate real-time, on-chain payments. Its blockchain-agnostic design supports multiple networks and stablecoins, offering flexibility and scalability. Additionally, x402's open standard promotes widespread adoption, enabling diverse applications across AI, APIs, and web services.

Who Are the Founders of x402?

The x402 Foundation was co-founded by Coinbase and Cloudflare, aiming to establish x402 as a universal standard for AI-driven payments. This collaboration leverages Coinbase's expertise in cryptocurrency and Cloudflare's internet infrastructure capabilities to create a robust and scalable payment protocol.
