X402 is a new protocol from Coinbase (launched in 2025) that uses the HTTP 402 "Payment Required" code to make instant payments using blockchain, particularly stablecoins such as USDC. Imagine: You request API access or web resources, the server responds with "pay first" via an HTTP header, you send the payment via your wallet, and you can access it immediately without the hassle of logging in or filling out forms. Ideal for AI agents, micro-payments, and seamless online transactions. Diterjemahkan dengan DeepL (
