x402 by Coinbasex402 is an open payment standard that enables AI agents and web services to autonomously pay for API access, data, and digital services.By leveraging the long-reserved HTTP 402 ”Payment Required” status code, x402 eliminates the need for API keys, subscriptions, and manual payment processing, allowing real-time, machine-native transactions using stablecoins like USDC.
