A new open-source payments standard for AI agents has moved under the Linux Foundation umbrella, with the newly-convened x402 Foundation drawing a 40-member roster that includes Visa, Mastercard, American Express, Stripe, Ripple, AWS, Google, Cloudflare and the Solana Foundation as premier members. Coinbase originally developed the x402 protocol, which is built around the long-dormant "402 Payment Required" HTTP response code and is designed to let AI agents, machines and humans transact natively over the web without subscriptions or manual card entry.
The foundation, roughly three months old and now operational, is searching for an executive director and has stood up a technical steering committee, with Alin Dragos of AWS Payments taking the board chairperson role.
Why it matters
The pitch is that AI agents will account for a large share of internet commerce, much of it in tiny micropayments that card fees make uneconomic. Alin Dragos, now board chair, framed the gap directly: "We solved the problem whereby participants on the internet can exchange information, but we don't actually have a good way to exchange value." Building that rail under a neutral steward rather than a single payments company is the bet that keeps x402 from collapsing into another walled garden. Stellar Development Foundation CEO Denelle Dixon, a veteran of the first open-browser era, drew the historical line bluntly: "You don't want to be in a walled garden when you're dealing with money."
Market impact
The premier-member list is the real signal for markets: it pairs the card networks and Stripe on one side with Circle, Ripple and the Solana Foundation on the other, so the same standard has to be acceptable to both rails. That breadth is what makes x402 a candidate foundation layer for agentic commerce rather than a Coinbase product. Watch the executive director hire and the first technical steering committee output; those will set whether x402 becomes a credible open standard or a marketing shell. Adoption will start with use cases agents already want, like per-call API payments and pay-per-crawl, before any consumer-facing surface appears.
Frequently asked questions
-
What is the x402 Foundation?
A newly-convened, Linux-affiliated foundation stewarding the x402 payments protocol for AI agents. It has roughly 40 members, a technical steering committee, and is searching for an executive director.
-
Who originally built the x402 protocol?
Coinbase originally developed x402, then handed stewardship to the eponymous foundation. The protocol is built around the long-dormant HTTP "402 Payment Required" response code.
-
Which companies are premier members of the foundation?
Visa, Mastercard, American Express, Stripe, Ripple, Adyen, Fiserv, Shopify, Google, AWS, Cloudflare, Circle, MoonPay and the Solana Foundation, alongside Coinbase.
-
Why does an AI-payments standard need blockchain rails?
Card fees make tiny micropayments uneconomic, which is the size of transaction AI agents will mostly make. Blockchain rails can settle those payments at low cost, which the foundation says finally unlocks agentic commerce.
-
What is the foundation actually shipping first?
It is standing up a technical steering committee and hiring an executive director. Early use cases are likely to be agent-to-agent payments like per-call API billing and pay-per-crawl.
