On April 2, the long-dormant status code "402 Payment Required" officially received its own foundation.
The Linux Foundation, a leading organization in the open-source community, has announced the launch of the x402 Foundation and the acceptance of Coinbase's contribution of the x402 protocol.
Announcing on April 2nd itself is a joke. More worth noting is the list of founding members released at the same time. Coinbase, Cloudflare, and Stripe jointly issued statements of support, while over twenty institutions, including Amazon Web Services, American Express, Google, Mastercard, Visa, Circle, Shopify, Microsoft, the Solana Foundation, and Polygon Labs, joined as initial members.
This list is truly star-studded—any one of these companies is a top player in finance, technology, or Web3 infrastructure.
Yet, ironically, most tokens related to the x402 ecosystem have plummeted by 80% to 98% from their highs. Amidst a technological concept collectively backed by industry giants and seemingly boundless potential, and a token price on the verge of collapse, this contradictory story is well worth telling.
The internet has a 30-year-old flaw.
Let’s be clear: 402 is not newly created—it revives an old rule that had been dormant for nearly 30 years.
In the 1990s, Tim Berners-Lee and his team included a status code in the HTTP protocol: 402 Payment Required. The meaning was straightforward—the server could tell the client, "Pay first, then receive the resource." But at the time, there was no suitable payment infrastructure, so 402 became the most famous placeholder in internet history.
Until Coinbase decided to activate it. Coinbase officially launched the x402 protocol in May 2025. Its logic is extremely simple: when a client (whether a person or an AI agent) requests a resource, the server responds with a 402 status code along with payment details; the client evaluates the price, initiates an on-chain USDC micropayment, and resubmits the request—all completed within seconds.
The elegance of this design lies in the fact that no account registration, no API key, and no pre-established billing relationship are required. The AI agent receives a 402 response, pays the fee, retrieves the resource, and continues working—all without human intervention.
Why has this become urgent in 2025? Because the explosion of AI Agents has fully exposed the structural contradictions in payment systems. McKinsey predicted in October 2025 that by 2030, agent commerce—where AI Agents autonomously represent merchants and consumers to complete transactions—will coordinate $3 trillion to $5 trillion in economic value.
The money is there, but there's no track. x402 is that track.
Why is it important to join the Linux Foundation?
The governance has changed—that's what matters most.
To turn an open-source project into an industry reference standard, you must demonstrate that its governance does not depend on any single vendor. Take the container orchestration platform Kubernetes, for example: originally developed by Google, its adoption surged dramatically after it was donated to the CNCF (under the Linux Foundation), ultimately becoming the industry standard for container orchestration. This path has been proven many times over.
Regarding x402, the transfer means three things. First, control of the protocol is handed over to the community; Coinbase cannot unilaterally modify protocol rules or embed commercial interests into the standard. As Jim Zemlin, CEO of the Linux Foundation, stated: “The x402 foundation will become an open, community-governed home, ensuring the protocol evolves in a transparent, interoperable, and broadly inclusive manner.”
Second, lower the compliance barrier for large institutions. Companies like Mastercard and American Express have strict legal requirements and are unlikely to approve infrastructure based on agreements with a single commercial entity. Once the protocol is governed by a neutral, nonprofit foundation, this barrier disappears.
Third, transferring the protocol to the Linux Foundation signals that this is a technological direction the entire industry is collectively betting on. Coinbase voluntarily relinquishes ownership of the protocol in exchange for industry-wide commitment to jointly build it.
The viability of this transaction hinges on Coinbase’s belief that the benefits it will gain as the largest participant in the ecosystem after x402 becomes a true internet standard far outweigh the cost of monopolizing the protocol itself.
What does this list of founding members indicate?
Reviewing the announcement from April 2, the list of founding members is well worth reading in detail.
22 founding members, spanning four dimensions, essentially outline the answer to the question: "Who is needed for AI Agent payments?"
The payment and financial networks form the most significant layer: Visa, Stripe, Mastercard, American Express, Adyen, Fiserv, Circle, PPRO, KakaoPay, and Ant International (Ant International is mentioned in Coinbase’s official announcement but not in the official graphic or Linux article). Together, these institutions process the vast majority of global consumer and merchant payment traffic.
Among them, Stripe is both a co-founder of the x402 Foundation and actively developing the Machine Payments Protocol, betting on both fronts. Visa’s statement is significant: Rubail Birwadker, Head of Global Growth Products and Strategic Partnerships at Visa, stated that Visa aims to ensure payments occur securely and seamlessly, regardless of where AI agents transact or whether they use credit cards or stablecoins.
On the cloud and infrastructure side, we have AWS, Google, Microsoft, and Cloudflare. AWS provides the hosted infrastructure AgentCore, which already has 402 reference implementations; Google Cloud’s AP2 protocol integrates x402 into the on-chain settlement layer. The lead for AWS AgentCore stated that for AI agents to function as autonomous participants in the digital economy, the ability to execute secure, frictionless payments is no longer optional—it is a foundational capability.
On the Web3 side are Coinbase, Base, Solana Foundation, Polygon Labs, Circle, and thirdweb.
The business application layer includes Shopify, Sierra, Merit Systems (developers of x402scan, MPPscan, and AgentCash), and Ampersend.ai, enabling integration of x402 into e-commerce, content, and data monetization scenarios.
Here we highlight Merit Systems and Ampersend.ai.
Merit Systems is a startup focused on Open Agentic Commerce, with products spanning multiple layers of the agentic commerce stack: discovery, developer tools, and mass-market applications—such as the x402 ecosystem browser x402scan, the MPP (Machine Payments Protocol) ecosystem browser MPPscan, AgentCash—a CLI and agent skill enabling AI agents to instantly access premium paid data and services—and Poncho, an AI-driven business automation tool.
Ampersend.ai is an agent economy control layer that officially launched on April 2, enabling each agent to create independent wallets and budgets for full control.
This diverse membership reflects several clear industry consensus points: First, AI-driven autonomous payments are an irreversible technological trend, and no major player is willing to miss out on this pivotal battle for the future of payments; second, open and neutral protocol standards form the foundation for cross-sector ecosystem collaboration, as proprietary solutions dominated by a single company cannot meet the needs of the entire industry; third, the payment systems of the future will inevitably be a fusion of traditional finance and blockchain technology—neither is opposed to the other, but rather complementary and symbiotic.
The concept is so strong—why has the related token dropped over 90%?
Now we reach the most delicate part.
First, let’s be clear: the x402 protocol has no native token. The settlement currency for the protocol is USDC. AI agents pay in USDC, and developers receive payments in USDC. The entire design philosophy of the protocol is to make payments as transparent as HTTP requests—there is no need for an “x402 token” to capture value.
Well-known x402 ecosystem tokens include PING (the first token minted via the x402 protocol), Daydreams (focused on building autonomous agents and applications on the x402 payment rail), and PAYAI (a payment verification infrastructure project), with token prices down 80%–98% from their previous highs.
On-chain data more directly reflects the cooling of the ecosystem. Daily transaction volume on x402 has dropped from a peak of approximately 3.8 million transactions in November 2025 to just tens of thousands today; daily trading volume has declined from over $2 million to recent levels of only $10,000 to $20,000.

This contrast between conceptual hype and lack of real-world adoption stems from several core misalignments in the crypto market:
Decoupling of Protocol Standards from Token Capture: A protocol's success does not guarantee that its native token will capture all value. When on-chain data shows no meaningful growth in usage, a market cap sustained solely by narrative will inevitably collapse. More critically, the x402 protocol itself has significant architectural limitations and application shortcomings—it lacks built-in fraud detection, tax calculation, and refund logic. For enterprise-grade AI agent scalability, these deficiencies are fatal flaws that undermine the token’s long-term value proposition.
2. Asymmetry between institutional entry and retail expectations: When AWS and Coinbase announce their entry, formal protocol development and commercial deployment may take years. The crypto market is accustomed to discounting narratives of "big things to come" in advance. When real-world adoption fails to keep pace with the expansion of these narratives, a correction follows.
3. Early Data Fabrication: Although the x402 ecosystem experienced explosive growth, Artemis’s analysis at the end of 2025 revealed that approximately 48% of transactions and 81% of trading volume on the x402 protocol were flagged as non-organic. The data is clear: the protocol’s “boom” was never fueled by genuine demand from the start. However, the situation is currently improving.
4. The sharp decline of the x402 concept token was also, to some extent, influenced by the overall market environment.
However, genuine agency business has far from arrived.
An honest conclusion
The launch of the x402 Foundation is a crucial step toward making this protocol a truly open standard. The presence of Visa, Mastercard, and Google on the list of initiators is no mere statement—it signifies that the x402 proposal has been recognized by traditional financial infrastructure as a direction worthy of active participation and shaping.
The fate of the x402 protocol ultimately depends on one simple thing: whether there are enough AI agents that genuinely need and can autonomously perform micropayments without human intervention.
The concept is real, and the future is real. But for investors, it’s essential to distinguish between "the triumph of technology" and "token speculation." An 88% drop is the bursting of a bubble, yet from the ruins, the foundational infrastructure of this AI economy has only just begun to emerge.
