HTTP 402 Finally Wakes Up: Coinbase Hands Its Payments Protocol to the Linux Foundation

Coinbase is teaming up with the Linux Foundation to launch the x402 Foundation, a new industry group that will oversee development of a web payments standard. The foundation will steward the x402 protocol, which allows websites to receive payments as part of normal web traffic, after Coinbase contributed the technology to the Linux Foundation for neutral governance. Because nothing says "we trust the community" quite like handing your code to the people who brought you Linux and still haven't fixed your printer drivers.

"The internet was built on open protocols," Linux Foundation Executive Director Jim Zemlin said in a statement. "The x402 Foundation will create an open, community-governed home to develop these capabilities in the open, ensuring they evolve with transparency, interoperability, and broad participation across the ecosystem." Zemlin also noted that this is significantly more exciting than the last time HTTP 402 was relevant, which was basically never.

Under Linux Foundation governance, the x402 protocol will remain vendor-neutral, allowing for transparent, community-driven growth while ensuring accessibility and supporting sustainability. In plain English: Coinbase built something cool, now it's everyone's problem to maintain. The dream of every open-source maintainer who just wanted to ship code and move on with their lives.

Erik Reppel, head of engineering for the Coinbase Developer Platform, said Coinbase will remain involved as a founding participant while the foundation manages development of the technology. "Coinbase is a founding member and the original creator of the protocol," Reppel told Decrypt. "Both Coinbase and Base are part of the initial set of industry participants supporting the foundation's migration to an open-source model." Basically, Coinbase is saying "we made this, we still care, but we figured letting Linux handle the politics might be healthier than doing it ourselves."

Launched in 2025 by Coinbase's developer platform, x402 revived the long-unused HTTP 402 "Payment Required" status code to create a native payment layer for the web. The protocol lets websites and APIs request payment directly during normal HTTP interactions before granting access to content or services. Developers have begun experimenting with the protocol as AI agents increasingly perform tasks for users online. After decades of HTTP 402 collecting dust like a Beanie Baby collection, someone's finally found a use for it. The code went from "lol what" to "wait, this could actually work" in record time.

Projects including Sam Altman's World are integrating x402 into tools that let agents prove they represent real people. Infrastructure efforts like MoonPay's Open Wallet Standard are also adding support for the protocol. Worldcoin's orb now has competition: proving you're human by paying small amounts of money. The future is weird and slightly dystopian, but at least it's monetized.

Companies participating in the launch of the x402 foundation include Google, Stripe, Visa, Mastercard, Shopify, Cloudflare, and the Solana Foundation. That's the equivalent of the Avengers assembling, if the Avengers were all companies that desperately want you to click "pay" more often.

"The shift toward agentic commerce requires cloud infrastructure that is as open as the protocols it supports," said James Tromans, Managing Director of Web3 and Digital Assets at Google Cloud. "By joining
