Coinbase and the Linux Foundation launched the x402 Foundation in 2025 to steward a new open-source internet payments standard. The group will manage the x402 protocol, which allows websites to request and receive payments as part of standard web traffic. This move shifts the technology from Coinbase's proprietary control to a neutral, community-governed model.
Enabling Agentic Commerce
The x402 protocol revives the long-dormant HTTP 402 "Payment Required" status code to create a native payment layer for the web. This allows APIs and websites to demand payment directly during HTTP interactions before granting access to services. Such a mechanism is critical for AI agents that perform autonomous tasks and require a way to pay for data or services without human intervention.
"Agents are going to buy, sell, and transact on our behalf. They will need a payment rail that’s open, interoperable, and doesn’t require a human clicking confirm purchase," Shan Aggarwal, chief business officer at Coinbase, told Decrypt.
Broad Industry Adoption
Several major technology and finance firms have joined the foundation, including Google, Stripe, Visa, Mastercard, Shopify, and Cloudflare. The Solana Foundation also participates, reporting that Solana has driven nearly 65% of x402 transaction volume this year. These participants aim to ensure the protocol remains vendor-neutral and interoperable across different cloud infrastructures.
"The shift toward agentic commerce requires cloud infrastructure that is as open as the protocols it supports," James Tromans, Managing Director of Web3 and Digital Assets at Google Cloud, said in a statement.
A Shift Toward Open Web Protocols
This initiative mirrors the early development of the internet, which relied on open protocols rather than closed corporate ecosystems. By moving x402 under the Linux Foundation, the industry avoids the fragmentation that often occurs when a single company controls a critical payment standard. This transition provides a transparent framework for developers to build pay-per-request models using stablecoins.
Infrastructure projects are already integrating the standard to enhance utility. Sam Altman's World project uses x402 to help agents prove they represent real people, while MoonPay's Open Wallet Standard is adding support. These early adoptions suggest a growing demand for standardized machine-to-machine financial rails.
Future Roadmap for x402
The x402 Foundation will now focus on maintaining interoperability across various technical implementations. Priority will be given to supporting merchants and developers who are building services around the pay-per-request model. The foundation remains open to any organization that contributes to or utilizes the technology.
Industry observers will watch whether this standard can achieve the same ubiquity as HTTPS or TCP/IP. The success of the foundation depends on its ability to onboard a critical mass of merchants and AI developers. If successful, x402 could become the primary financial layer for the autonomous agent economy.
