Top Tokens: x402

x402 is an open-source protocol developed by Coinbase for micropayments on the internet by leveraging the HTTP 402 status code ("Payment Required") alongside stablecoins like USDC. 

It creates a seamless, native payment rail for automated clients and AI agents, enabling them to directly compensate for access to APIs, data streams, computational resources, or content in real-time without the need for traditional intermediaries, accounts, or subscriptions. By embedding payment logic into standard HTTP requests and responses, x402 facilitates frictionless, low-cost transactions—often fractions of a cent—fostering a more dynamic Web3 economy where machine-to-machine interactions can autonomously settle value on demand, powering innovations in AI-driven services, decentralized cloud computing, and agentic workflows.
