At its core, the foundation’s mission is simple: promote adoption of the x402 protocol, a new standard that allows machines, websites, and services to exchange value over the web using the same “language.”
This effort arrives as the internet shifts from human-driven browsing to software-driven transactions. As AI assistants, bots, and autonomous services take on more tasks, the need for a universal way for machines to pay each other is becoming urgent. That’s what the x402 protocol wants to be.
Why x402 Matters?
Today, websites often respond to automated traffic with an HTTP 402 code: “Payment Required.” It is a signal sent billions of times daily by sites running on Cloudflare. But the message usually goes nowhere because there is no clear standard for what that payment should look like or how it should be processed.

That is where x402 comes in. Originally outlined by Coinbase, the x402 protocol provides a structured flow for handling payments online. When a client requests access to a resource, the server can respond with clear instructions about how much to pay and where to send it. The client then makes the payment, and once verified, the server releases the content.
🚀 Big news 🚀 @coinbase and @cloudflare will be launching the x402 Foundation to establish x402 as the universal standard for AI-driven payments.

For investors and developers, the promise is significant. Instead of relying on subscriptions or locked-down APIs, digital services can be monetized directly, one transaction at a time. Imagine an AI assistant that buys an accessory for your Halloween costume across multiple shops, or a trading bot that pays small amounts for real-time financial data without committing to expensive monthly fees. These scenarios point to a future where value flows as easily as information.
Ok, let me try explaining (mostly to myself) what the x402 protocol, launched by Coinbase, means:
✔️ When you type a URL into the browser, your browser (“the client”) tries connecting to a server that hosts the website (e.g., Bloomberg). If it successfully connects, the server… https://t.co/GQOLosCcOE pic.twitter.com/ZSOcfJo8UZ— Jevgenijs Kazanins (@jevgenijs) September 23, 2025
From Testnets to Real-World Adoption
Cloudflare is already moving beyond theory with new tools for developers. Its Agents SDK and MCP integrations now support x402 payments. A live demo called the x402 playground lets developers test the protocol using Testnet USDC on Base, Coinbase’s blockchain network. This hands-on experience shows how agents can interpret payment instructions, decide whether to proceed, and settle transactions instantly.
We’re launching the x402 Foundation with @Cloudflare.
I’ve been thinking about how internet payments should work for years. Or more specifically, how they aren’t working, and need to improve.

The foundation is also pushing for flexibility. A new “deferred payment scheme” is being tested in Cloudflare’s pay-per-crawl beta. Instead of settling each transaction immediately, crawlers can generate logs and pay a single daily bill. This mirrors traditional finance practices and makes it easier to handle disputes or batch settlements.
