Coinbase has unveiled the x402 standard, a revamped version of the HTTP 402 'Payment Required' status code, designed to facilitate blockchain-based payments directly on the web. This new protocol enables transactions using stablecoins like USDC within HTTP requests, bypassing traditional third-party payment gateways. The initiative aims to streamline online transactions, making them as simple as data transfers. Early applications of the x402 standard include payments for AI agents, IPFS storage, and browser-based content access. Coinbase has collaborated with major industry players such as Cloudflare, Google, and Visa to integrate and promote this innovative payment standard.
