Coinbase has introduced a new payment system labeled X402, allowing cryptocurrency transactions to be processed over HTTP, specifically designed for AI applications and APIs. This development aims to enhance the integration of crypto payments in digital services, making it easier for developers to incorporate cryptocurrency transactions into their platforms.
Coinbase has introduced the x402 protocol, transforming the long-unused HTTP 402 status code into a payment layer that enables AI agents to autonomously process payments without human intervention. This innovation facilitates a more efficient system for digital transactions, allowing servers to request payments and clients, including AI agents, to respond using stablecoins like USDC. Other major companies like Visa and PayPal are also exploring similar autonomous payment solutions for AI-driven commerce.
