Coinbase and the Linux Foundation launched the x402 Foundation to oversee a new open-source internet payments standard. This industry group will manage the x402 protocol, which allows websites to request and receive payments as part of standard web traffic. The move follows Coinbase's decision to contribute the technology to a neutral governance model to encourage broad adoption.
Enabling Autonomous 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 request payments directly during HTTP interactions before granting access to specific services or content. This technical framework is particularly critical for AI agents that perform tasks for users without requiring manual 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 and Integration
A diverse group of technology and finance leaders joined the foundation, including Google, Stripe, Visa, Mastercard, Shopify, and Cloudflare. The Solana Foundation also participated, noting that Solana has already driven nearly 65% of x402 transaction volume this year. Other integrations include Sam Altman's World project and MoonPay's Open Wallet Standard.
"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.
Transition to Open Governance
By moving the protocol under the Linux Foundation, the x402 standard remains vendor-neutral and accessible to all developers. This shift mirrors how the early internet was built on open protocols rather than proprietary systems. The foundation will now prioritize maintaining interoperability across different implementations and supporting merchants who build services around the standard.
Erik Reppel, head of engineering for the Coinbase Developer Platform, confirmed that Coinbase and its network, Base, will remain founding participants. The transition ensures that the evolution of the protocol is driven by community consensus rather than a single corporate entity. This approach is intended to foster a sustainable ecosystem for pay-per-request models using stablecoins.
The Future of Machine-to-Machine Payments
The success of x402 could redefine how digital services are monetized, moving away from monthly subscriptions toward granular, request-based payments. As AI agents become more autonomous, the demand for a standardized, machine-readable payment layer will likely increase. Observers should watch for the rate of adoption among major cloud providers and the integration of the protocol into mainstream AI frameworks.
