Coinbase, Cloudflare and Stripe announced on April 2 the creation of the x402 Foundation, a non-profit organization that will manage the x402 payments protocol as an open internet standard and brought together 23 founding companies including Google, Microsoft, Amazon Web Services, Visa, Mastercard, American Express, Shopify and the Solana Foundation.
The x402 Foundation, in turn, will operate under the orbit of the Linux Foundation, the same organization behind the eponymous operating system.
The goal of the x402 Foundation is that any application, service or software agent can send and receive payments online automaticallywithout registrations, subscriptions or human intervention, in the same way that data or emails are exchanged today.
According to the releasethis new organization guarantees that no company owns the protocol x402 and that any developer, startup or company can build on it without depending on a centralized provider.
Until now, x402 was a Coinbase proposal launched in May 2025, as reported by CriptoNoticias. With the creation of the foundation, the protocol ceases to be a corporate project and begins to have a neutral governance and institutional support of the world’s leading payments and digital infrastructure players.
According to the announcement, the x420 Foundation is open to new members: developers, startups and global companies can join to contribute to the development of the protocol.
What is the x402 protocol for?
x402 works on the HTTP code 402a state called «Payment Required» (Payment Required) that has existed in the web protocol since its origins but never had a standardized implementation. x402 activates it and turns it into a payment channel functional between applications.
According to your whitepaperx402 “enables AI agents and web services to autonomously pay for access to APIs, data, and digital services.”
That eliminates the need for access keys, subscriptions or manual payment processes. In practical terms, any app can enable payments per use with just one line of code, and the system is mainly designed to work with stablecoins such as USDC, which guarantees immediate liquidity and a stable price linked to the dollar.
The core use case is artificial intelligence agents: programs that operate autonomously on behalf of a user and that need to pay for services without a person authorizing each transaction. With x402, the agent receives the price, pays and agrees. Everything in seconds, without forms or intermediaries.
The creation of the x402 Foundation turns a Coinbase proposal into an institutionally backed project on a global scale. The protocol now has neutral governance, a coalition of members ranging from tech giants to traditional payment networks, and a proven standards infrastructure behind it.
What remains to be demonstrated is whether that coalition translates into real adoption, how many services will implement x402, when and with which payment rails.
