Coinbase, Cloudflare, and Stripe launch x402 foundation to pioneer open-source financial plumbing for autonomous AI agent transactions

Coinbase, Cloudflare, and Stripe have partnered with the Linux Foundation to launch the x402 Foundation, a nonprofit body that will steward x402, an open, vendor-neutral payment standard designed for autonomous AI agents, APIs, and applications. The protocol embeds payments directly into HTTP interactions by standardizing use of the HTTP 402 "Payment Required" response code, allowing software clients to automatically send and receive value as part of normal web requests without human intervention. Originally created by Coinbase, x402 is being contributed to the Linux Foundation so that no single company controls the standard, with governance handled through an open, community-driven model. The initiative is pitched as foundational "financial plumbing" for machine-to-machine and AI-driven commerce, addressing the current fragmentation and proprietary nature of online payments. x402 is designed to support both fiat and crypto rails across multiple payment networks and blockchains, so that AI agents or services can pay for APIs, compute, and other resources programmatically, similar to how they exchange data over HTTP today. The x402 Foundation is launching with a broad coalition of industry participants across payments, cloud, and Web3— including Adyen, AWS, American Express, Ant International, Base, Circle, Google, KakaoPay, Mastercard, Microsoft, Polygon Labs, Shopify, Solana Foundation, Stripe, Visa, and others — positioning x402 as one of the leading contenders to become a default standard for agentic and internet-native payments. This matters for crypto/Web3 and fintech because it attempts to standardize how value moves natively over the web at the protocol layer, rather than through siloed payment gateways. If widely adopted, x402 could give AI agents and on-chain applications a common way to charge for and pay for services in small, automated increments, while letting different rails (card networks, bank payments, stablecoins, multiple blockchains) plug into the same open interface. By situating x402 under the Linux Foundation, the backers are explicitly framing it as an open infrastructure standard—analogous to HTTP or SMTP for data and email—rather than a proprietary product, which is intended to encourage adoption by diverse payment providers, Web3 projects, and large internet platforms.
