Coinbase, amongst others, stuffed that hole in Could 2025. Below x402, a server that desires fee solutions a request with a 402 and a value. The consumer indicators a stablecoin switch, often USDC, resends the request with the fee hooked up, and will get the information. The trade takes seconds and desires no account, no card, and no prior relationship between the 2 sides.
That’s the reason the AI trade cares. An autonomous agent can’t open a checking account, cross a credit score test or signal a SaaS contract, however can signal a transaction. Google has wired x402 into its personal agent funds protocol, and Cloudflare ships it in its agent toolkit.
