x402: Internet-Native Payment Standard for AI Agents
kleffew94 · x · 2026-08-28
x402 is an open, neutral standard for internet-native payments designed for the agentic future. It integrates natively with HTTP (e.g., status code 402) to enable direct value transfer between clients and servers. Featuring zero protocol fees, zero wait, and decentralization, it allows developers to require payments for endpoints with a single line of code, ideal for autonomous AI agent transactions.
