Coinbase and the Linux Foundation have partnered to launch the x402 Foundation, an industry group dedicated to overseeing a new open-source internet payments standard. The foundation will manage the x402 protocol, which allows websites to request and receive payments as part of standard web traffic. This transition moves the technology from Coinbase's proprietary control to a neutral governance model to encourage broad adoption.
Reviving the HTTP 402 Status Code
The x402 protocol, originally launched in 2025 by the Coinbase Developer Platform, repurposes the long-dormant HTTP 402 "Payment Required" status code. This creates a native payment layer for the web, enabling APIs and websites to request payment directly during HTTP interactions before granting access to services. By integrating payments into the transport layer, the protocol removes the need for traditional checkout redirects.
"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."
Enabling Agentic Commerce and AI
The push for a standardized payment rail is driven largely by the rise of AI agents that perform autonomous tasks for users. These agents require a way to pay for services without human intervention or manual confirmation clicks. Early adopters include Sam Altman's World project and MoonPay's Open Wallet Standard, both of which are integrating x402 to facilitate these machine-to-machine transactions.
Industry giants have already joined the foundation to ensure the standard remains interoperable. Participating organizations include Google, Stripe, Visa, Mastercard, Shopify, and Cloudflare. The Solana Foundation is also a key participant, with Rishin Sharma noting that Solana has driven nearly 65% of x402 transaction volume this year.
Shifting Toward Vendor-Neutral Infrastructure
This move mirrors historical shifts in the tech industry where foundational infrastructure is handed to non-profit bodies to prevent market fragmentation. By placing x402 under the Linux Foundation, the protocol avoids being tied to a single corporate entity, which traditionally makes large enterprises more comfortable with adoption. This neutral ground allows competing payment processors to collaborate on the underlying rail while competing on the services built atop it.
"Agents are going to buy, sell, and transact on our behalf," Shan Aggarwal, chief business officer at Coinbase, told Decrypt. "They will need a payment rail that’s open, interoperable, and doesn’t require a human clicking confirm purchase."
Future Outlook for Web Payments
The x402 Foundation will now focus on maintaining interoperability across different technical implementations and supporting merchants in building pay-per-request models. The integration of stablecoins is expected to be a primary focus for developers looking to reduce transaction costs for micro-payments. Observers will be watching whether this standard can achieve the same ubiquity as HTTPS to redefine how value moves across the internet.
