Coinbase and Cloudflare have teamed up to launch the x402 Foundation, a new initiative aimed at building a universal standard for AI-powered payments across the web.
Key Takeaways
- Coinbase and Cloudflare announced the x402 Foundation, focused on advancing the x402 protocol for machine-to-machine and AI-driven payments.
- x402 revives the unused HTTP 402 status code, allowing websites and digital agents to negotiate payments in real time.
- The protocol supports micropayments, agentic commerce, and pay-per-use models, unlocking new monetization strategies.
- Cloudflare is integrating x402 into its developer tools and testing a deferred payment scheme, expanding flexibility for use cases.
What Happened?
Cloudflare and Coinbase have launched the x402 Foundation to push forward the adoption of a new open payments protocol called x402, designed to enable seamless financial transactions between AI agents, websites, and services. The foundation’s mission is to make x402 a neutral, widely adopted standard for embedding value exchange into internet interactions, especially in an era increasingly dominated by software-driven automation.
🚀 Big news 🚀 @coinbase and @cloudflare will be launching the x402 Foundation to establish x402 as the universal standard for AI-driven payments.

A Protocol Built for the Machine Economy
The internet was originally designed for people, not machines. Traditional payment systems often rely on subscriptions, logins, and API keys, which can’t scale to meet the needs of autonomous agents or automated workflows. The x402 protocol aims to solve this by updating the largely unused HTTP 402 “Payment Required” status code, giving it real-world utility in automated environments.
With x402, when a digital agent or AI service requests access to a resource, the server responds with payment instructions via a 402 code. The client then makes a payment and gains access upon verification. This unlocks real-time, per-request monetization without human intervention.
Use Cases Already Emerging
The x402 protocol is already being piloted in several areas:
- Pay-per-use AI and content: Accessing models, research, and media without subscriptions.
- Autonomous AI agents: Bots that transact for data, services, and compute without user action.
- Micropayments: Tipping creators, buying content, or accessing APIs on a per-call basis.
- Deferred billing: A new scheme in testing allows batch payments at the end of a usage period, simplifying accounting and dispute resolution.
- High-frequency trading bots: Paying in real time for premium financial data without monthly commitments.
Cloudflare and Coinbase: Shared Vision, Split Roles
Coinbase, which initially conceptualized the x402 transaction flow, brings its stablecoin expertise and blockchain infrastructure into the mix, enabling fast and secure settlements. Meanwhile, Cloudflare is integrating the protocol into its Agents SDK and Model Context Protocol (MCP) to support machine-driven web interactions.
Cloudflare has also launched a public x402 playground on Coinbase’s Base testnet, allowing developers to explore how AI agents interpret and act on payment instructions. As part of this rollout, Cloudflare is experimenting with a deferred payments model for web crawlers and content scrapers, letting them operate now and settle later.
A Foundation for the Future
The newly formed x402 Foundation will serve as the steward of the protocol, ensuring open governance, encouraging contributions from the developer community, and supporting a broad range of payment methods including stablecoins, credit cards, and bank transfers in future iterations.
Additional members will be added over time, including companies actively using x402 in production, AI firms developing large language models, e-commerce platforms, and more. Both Cloudflare and Coinbase have emphasized the importance of interoperability and transparency as key pillars of the initiative.
CoinLaw’s Takeaway
In my experience covering fintech and crypto, few announcements feel as foundational as this one. What Coinbase and Cloudflare are doing with x402 is more than just a new tool. It’s laying the groundwork for an entirely new economy powered by autonomous agents. We’re talking about a world where bots not only fetch data or complete tasks but negotiate and pay for services on the fly. This isn’t a sci-fi vision anymore. The tech is here, and x402 could be the thread that ties it all together. I found the use of an old HTTP status code particularly clever. It’s elegant, efficient, and incredibly timely.
