Detailed Factual Report
Nobody really built the web with payments in mind. Early HTTP specifications included a status code, 402 "Payment Required", that was reserved for a future system of online payments. Then it sat unused for about 30 years. Payments were slow and expensive, and they needed accounts, card details and middlemen who could reverse charges. None of that works for a small payment made by software.
x402 is an attempt to finally give the internet a native way to pay. This guide covers what it is, how it works, who backs it, and whether there's a token involved.
The 402 "Payment Required" code has been in the HTTP standard since the 1990s. It was set aside "for future use", and x402 is the first big effort to actually use it.
x402 is an open payment standard built on top of HTTP, the protocol that moves data around the web. Coinbase launched it in May 2025 with partners including AWS, Anthropic, Circle and NEAR. It lets APIs, apps and AI agents pay for services in stablecoins as part of an ordinary web request.
