Coinbase and the Linux Foundation have launched 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 and APIs to request payments directly within standard web traffic. This move transitions the technology from a Coinbase-led project to a neutral, community-governed model.
Reviving the Payment Required Status Code
The x402 protocol, introduced in 2025, utilizes the long-dormant HTTP 402 "Payment Required" status code to create a native payment layer for the web. According to Decrypt, this allows services to request payment during normal HTTP interactions before granting access to content. This mechanism removes the need for manual human intervention during the checkout process.
Several major tech and financial firms have joined the foundation, including Google, Stripe, Visa, Mastercard, Shopify, and Cloudflare. The Solana Foundation is also a participant, reporting that Solana has driven nearly 65% of x402 transaction volume this year. These partners aim to ensure the protocol remains vendor-neutral and interoperable across different platforms.
"The internet was built on open protocols," Linux Foundation Executive Director Jim Zemlin said in a statement reported by Decrypt.
Enabling Agentic Commerce
The primary driver for the x402 standard is the rise of agentic commerce, where AI agents perform tasks and transactions on behalf of users. These agents require a payment rail that does not require a human to click a confirmation button for every single request. The protocol is already being integrated into tools like Sam Altman's World and MoonPay's Open Wallet Standard.
This push toward autonomous transactions aligns with broader industry trends in AI capabilities. For instance, Google's Gemma 4 models are specifically designed for agentic workflows, featuring native support for function calling to help agents plan and complete tasks. While Gemma 4 provides the intelligence to navigate apps, x402 provides the financial infrastructure to pay for the services those apps provide.
"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.
Infrastructure for Autonomous AI
This development marks a shift toward a more modular AI ecosystem where intelligence and payment layers are decoupled but interoperable. By placing the protocol under the Linux Foundation, the industry avoids the risk of a single company controlling the financial gateways for AI agents. This mirrors the early development of the web, where open standards allowed for rapid, diverse growth.
Google Cloud's involvement highlights the necessity of cloud infrastructure that supports these open protocols. James Tromans, Managing Director of Web3 and Digital Assets at Google Cloud, stated that the company is reinforcing its commitment to secure, AI-driven transactions. The integration of stablecoins is expected to be a key component in making these micro-payments efficient.
Future Outlook for Web Payments
The x402 Foundation will now focus on maintaining interoperability and supporting developers who build services around the standard. As AI models like Gemma 4 become more efficient on edge devices, the demand for a seamless, machine-to-machine payment layer will likely increase. The success of the foundation depends on broad adoption by merchants and API providers.
Industry observers should watch for the rollout of more "pay-per-request" models for AI services. If x402 becomes the dominant standard, it could fundamentally change how digital content is monetized, moving away from monthly subscriptions toward granular, usage-based payments executed by autonomous agents.
