On April 2, that status code “402 Payment Required,” which had been shelved for 30 years, officially got its own foundation.

A benchmark institution in the open-source space, the Linux Foundation, announced the launch of the x402 Foundation and is also accepting the handoff of Coinbase’s contributions to the x402 protocol.

Choosing April 2 to announce it is itself a joke. What’s even more worth reading closely is the founding members list released at the same time. Coinbase, Cloudflare, and Stripe jointly issued a support statement. More than 20 organizations joined the initial member lineup, including Amazon Web Services, American Express, Google, Mastercard, Visa, Circle, Shopify, Microsoft, the Solana Foundation, Polygon Labs, and others.

This list can only be described as “a galaxy of stars.” Pull out any few names at random, and they’re top-tier players in the finance, technology, and Web3 infrastructure sectors.

However, the irony is that most x402 ecosystem-related tokens have fallen from their highs by 80%-98%. On one side, it’s a technology concept that industry giants have collectively bet on and that seems to have limitless prospects. On the other side, it’s token prices that are nearly in free fall. This contradictory story is worth telling properly.

A 30-year “hole” in the internet

First, let’s make one thing clear: 402 wasn’t newly invented—it revived an old rule that had been shelved for nearly 30 years.

In the 1990s, when Tim Berners-Lee and his team were defining the HTTP protocol, they wrote in a status code: 402 Payment Required. The meaning was straightforward: the server could tell the client, “Pay first, then get the resource.” But back then, there was no suitable payment infrastructure, so 402 became what’s arguably the internet’s most famous “placeholder” in history.

Until Coinbase decided to activate it. Coinbase formally launched the x402 protocol in May 2025. Its logic is extremely simple: when a client (which can be a human or an AI Agent) requests a resource, the server returns a 402 status code along with payment specifications; the client evaluates the price, initiates a micro-payment on-chain in USDC, and then re-submits the request—everything completes within seconds.

The elegance of this design lies in the fact that you don’t need to register an account, don’t need an API Key, and don’t need to set up a billing relationship in advance. An AI Agent reads the 402 response, pays, gets the resource, and keeps working—no human intervention at any point.

Why did this suddenly become urgent in 2025? Because the explosion of AI Agents has fully exposed the structural contradictions in payment systems. In October 2025, McKinsey predicted that by 2030, Agent commerce—meaning AI Agents autonomously representing merchants and consumers to complete transactions—will coordinate and process $3 trillion to $5 trillion in economic value.

The money is there, but there’s no track. x402 is that track.

Why it’s important to join the Linux Foundation

Governance has changed—this is the most important thing.

To push an open-source project into becoming an industry reference standard, you need to prove that its governance does not rely on any single vendor. Take Kubernetes as an example: it was initially developed by Google. After it was donated to CNCF (an arm of the Linux Foundation), adoption surged rapidly, and it ultimately became the industry standard for container orchestration. This path has been validated many times.

Specifically for x402, the handoff means three things. First, control of the protocol goes to the community—Coinbase can’t unilaterally change protocol rules or embed commercial interests into the standard. As Linux Foundation CEO Jim Zemlin put it: “The x402 Foundation will become an open, community-governed home, ensuring the protocol evolves in a transparent, interoperable, and broadly participatory way.”

Second, it lowers the compliance barrier for large institutions. Companies like Mastercard and American Express have strict legal requirements, and they’re unlikely to approve infrastructure that “depends on a single commercial company protocol.” Once the protocol is owned by a neutral nonprofit foundation, that barrier disappears.

Third, transferring the protocol to the Linux Foundation sends a signal: this is a technical direction the whole industry is jointly betting on. By proactively giving up ownership of the protocol, Coinbase gains the entire industry’s willingness to build it together.

The premise that makes this deal worthwhile is that Coinbase believes the upside it will receive as the largest ecosystem participant after x402 becomes a true internet standard far outweighs the cost of monopolizing the protocol itself.

What this founding members list says

Looking back at the April 2 announcement, the founding members list is well worth a close read.

With 22 founding members across four dimensions, it basically answers the question of “who AI Agent payments require.”

The heaviest weight is the layer of payments and financial networks: Visa, Stripe, Mastercard, American Express, Adyen, Fiserv, Circle, PPRO, KakaoPay, Ant International (Ant International appears in Coinbase’s official announcement text, but it’s not mentioned in the official announcement graphic and the Linux Foundation materials). Together, these institutions handle the vast majority of consumer and merchant payment traffic worldwide.

Among them, Stripe is both a co-founding initiator of the x402 Foundation and also pushing the Machine Payments Protocol (two-sided bets). Visa’s position is particularly meaningful: Visa’s global growth product lead and strategic partner Rubail Birwadker said Visa’s goal is to ensure that, no matter where AI Agents transact—whether using credit cards or stablecoins—payments can happen safely and seamlessly.

On the cloud & infrastructure side are AWS, Google, Microsoft, and Cloudflare. AWS provides the hosted infrastructure for building, deploying, and operating production-grade AI Agents; AgentCore already has an x402 reference implementation. Google Cloud’s AP2 protocol will bring x402 into the on-chain settlement layer. An AWS AgentCore leader said AI Agents, as autonomous participants in the digital economy, no longer can have “safe, frictionless payments” as an optional feature—it has become a core capability.

On the Web3 side are Coinbase, Base, Solana Foundation, Polygon Labs, Circle, and thirdweb.

The commercial application layer includes Shopify, Sierra, Merit Systems (which developed x402scan, MPPscan, and AgentCash), and Ampersend.ai—these can integrate x402 into e-commerce, content, and data-creation scenarios.

Here we want to highlight Merit Systems and Ampersend.ai.

Merit Systems is a startup focused on Open Agentic Commerce (open agent commerce / intelligent agent commerce). Its product covers multiple layers across the agent commerce stack: Discovery, developer tools, and mainstream applications. For example, the ecosystem browser x402scan for the x402 ecosystem; the ecosystem browser MPPscan for MPP (Machine Payments Protocol); AgentCash, a CLI and agent skill that enables AI agents to access premium paid data and services instantly; and Poncho, an AI-driven business automation tool.

Ampersend.ai is an agent-economy control layer, and it officially launched on April 2. It supports each Agent creating its own independent wallet and budget, enabling complete control.

This kind of diversified member composition conveys several clear industry consensus points: first, autonomous AI payments are an irreversible technological trend, and no major player is willing to stay out of this future payments war; second, open, neutral protocol standards are the foundation for cross-domain ecosystem collaboration, and closed solutions led by a single enterprise are hard to adapt to the needs of the whole industry; third, the payment system of the future must be a fusion of traditional finance and blockchain technology—these are not in opposition but rather complementary and symbiotic.

With such a good concept, why have related tokens fallen more than 90%?

Now we’re at the most delicate part.

First, make one thing clear: the x402 protocol has no official token. The settlement currency of the protocol is USDC. AI Agent payments use USDC, and developer payouts also use USDC. The design philosophy of the entire protocol is to make payments as transparent as HTTP requests—it basically doesn’t need an “x402 token” to capture value.

People are already familiar with x402 ecosystem tokens, including PING (the first token minted via the x402 protocol), Daydreams (built on the x402 payment track for autonomous agents and applications), and PAYAI (a payment verification infrastructure project). Token prices are down 80%-98% from their previous highs.

On-chain data can reflect ecosystem cooling even more directly. The number of daily transactions on x402 has shrunk from around 3.8 million at the peak in November 2025 to just tens of thousands today. Daily transaction volume has fallen from more than $30k to roughly one or two recent tens of thousands of dollars.

This contrast of “concept-hot, execution-cold” is behind several key logical mismatches in the crypto market:

1. Decoupling between “protocol standards” and “token capture”: A protocol’s success does not automatically mean some ecosystem token can capture all the value. When on-chain data shows there’s no real application growth, market cap supported solely by narratives will naturally collapse. More importantly, the x402 protocol itself has obvious architectural limitations and application shortcomings—no built-in fraud detection, tax calculation, or refund logic. For scaling enterprise-level AI Agent applications, these defects are enough to be fatal weaknesses, making it difficult to support long-term token value expectations.

2. Asymmetry between institutional entry and retail expectations: When AWS and Coinbase announced they were coming in, formal protocol development and commercial rollout might take years. The crypto market is used to discounting, in advance, narratives that “the future will be big.” When actual adoption doesn’t keep pace with narrative expansion, the correction arrives.

3. Early data was fabricated: Although the x402 ecosystem once saw explosive growth, an Artemis analysis at the end of 2025 found that about 48% of x402 protocol transactions and 81% of成交 volume were flagged as non-organic. The data is very clear: the protocol’s “prosperity” from the beginning was not supported by real demand. But the situation is improving for now.

4. The sharp plunge of x402 concept tokens is also, to some extent, dragged down by the overall market environment.

But there’s no question: real agent commerce activity has not arrived yet.

An honest conclusion

The launch of the x402 Foundation is a crucial step toward making the protocol a truly open standard. The fact that Visa, Mastercard, and Google appear simultaneously on the initiator list is not something said casually—it means the x402 proposal has been recognized by traditional financial infrastructure as a direction “worth participating in shaping.”

The fate of the x402 protocol ultimately depends on one simple thing: whether there are enough AI Agents that truly need and can complete micro-payments autonomously without human intervention.

The concept is real, and so is the future. But for investors, they must distinguish between “a technological victory” and “token speculation.” A 98% drop represents the burst of a bubble, but on top of the ruins, this AI economy’s underlying infrastructure is only just starting to break ground.
