Everything You Need to Know about x402: The 30-Year-Old HTTP Code Built for the AI Economy
summary
x402 repurposes the reserved 402 status code into an open HTTP-native payments standard under the Linux Foundation, backed by Visa, Stripe, Cloudflare and Microsoft, that attaches a stablecoin transfer to any HTTP request. It is permissionless, multi-chain and multi-token, runs with two lines of code or three clicks to connect a wallet, supports pay-per-use APIs and agentic commerce, and settles for < $0.01 per tx in live demos.
