Coinbase Competes to Power Stablecoin Payments for AI Agents on Cloudflare
Coinbase is competing with fintech startup Zerohash to issue a stablecoin designed specifically for AI agent transactions on Cloudflare's network. The report was first published by The Information and later confirmed by Reuters. What makes this contract so important is Cloudflare's scale: its infrastructure handles roughly 20% of all web traffic, giving the winning company a powerful integration point inside a major layer of the internet.
The proposed stablecoin arrangement is centered on a growing need in AI infrastructure. As autonomous software agents begin handling tasks, purchasing data, calling APIs, and completing machine-to-machine transactions, they need a payment rail that works natively online. A stablecoin purpose-built for these interactions would give AI agents a way to pay instantly and cheaply across Cloudflare's network without relying on slower, more expensive traditional systems.
x402 Foundation Revives HTTP 402 for Embedded Web Payments
What the x402 Foundation is designed to do
Coinbase and Cloudflare already have a broader collaboration in place through the x402 Foundation. The initiative revives the long-dormant HTTP 402 "Payment Required" status code and turns it into a practical framework for embedding stablecoin payments directly into standard web requests.
This matters because it shifts payments from being a separate step into being part of the request itself. Instead of forcing users or machines through account creation, API key management, or card-based billing flows, the protocol aims to make payment a native part of how digital services are accessed. That changes the shape of online commerce, especially for automated systems that need speed, low friction, and constant availability.
How x402 changes API payments
Coinbase CEO Brian Armstrong described the protocol in direct terms: "x402 lets you make any API call with payment embedded right in the API call itself. No sign up, API key, or credit card required". That framing captures the heart of the model. The API request and the payment happen together, which removes several layers of operational friction.
For AI agents, that's a big deal. They don't work like human customers browsing checkout pages. They need a lightweight mechanism to pay for access, data, compute, or services in real time. Embedding payment inside the API call creates a cleaner path for autonomous transactions and opens the door to internet-native machine commerce.
x402 Foundation backers expand industry credibility
The x402 Foundation is backed not only by Coinbase and Cloudflare, but also by Circle, AWS, Stripe, and Google. That list gives the initiative added credibility because it spans stablecoin infrastructure, cloud computing, payments, and large-scale internet services.
The involvement of these companies suggests that x402 is being positioned as more than an experiment. It points to a coordinated attempt to establish a payment layer that works across the modern web and supports both developers and autonomous systems operating online.
Cloudflare Stock Rises as AI Payments and Security Catalysts Converge
Shares of Cloudflare rose roughly 7% on March 18, closing at $225.48 according to Investing.com. The move came as several positive developments hit at once, with investors responding to both the AI payments narrative and fresh momentum in cybersecurity.
The stock rally reflected growing belief that Cloudflare is becoming more than a cloud security provider. It is increasingly being viewed as core infrastructure for the next phase of internet activity, where AI agents, machine-to-machine communication, and automated payments all sit on top of secure global networks. Over the past year, Cloudflare shares have nearly doubled, driven by enthusiasm around its role at the intersection of cloud security and the emerging machine economy.
SentinelOne and Cloudflare Expand Cybersecurity Integration
New telemetry integration with Singularity AI SIEM
Cloudflare and SentinelOne expanded their cybersecurity partnership by integrating Cloudflare's global edge network telemetry into SentinelOne's Singularity AI SIEM platform. The integration feeds Cloudflare's Zero Trust, Gateway, Access, and WAF logs directly into SentinelOne's system.
That creates what the companies described as a "single, unified command center" for automated threat detection. In practical terms, it means security teams can work from a more centralized environment, with data from Cloudflare's network edge flowing into SentinelOne's detection and analysis framework.
Why the SentinelOne partnership strengthened sentiment
The expanded partnership added another reason for investors to view Cloudflare as strategic infrastructure. Cloudflare is not only trying to support AI-driven payments and web-based autonomous activity. It is also deepening its place in enterprise security workflows.
That combination matters. A company that controls a global edge network, supports web security, and potentially enables machine-native payment rails starts to look like a foundational layer rather than a point solution. And that's exactly the kind of story that tends to drive strong market interest.
Cloudflare Threat Intelligence Report Highlights Massive Daily Threat Volume
Cloudflare's inaugural 2026 Threat Intelligence Report, released in early March, added more context to the cybersecurity narrative. The report said the company's network blocks more than 230 billion threats daily on average.
The report also detailed activity by nation-state actors, including Chinese-affiliated groups tracked as Salt Typhoon and Linen Typhoon. According to the findings, these groups are pre-positioning inside North American telecommunications and government networks for long-term geopolitical leverage. That kind of threat environment underscores why network-level visibility and automated detection tools are becoming more important, and why partnerships like the one with SentinelOne are landing with investors.
Why AI Agent Payments Need Low-Cost Stablecoin Infrastructure
Traditional payment fees break the micropayment model
The larger thesis connecting these developments is Cloudflare's view that its network can become a base layer for autonomous machine commerce. That idea depends on solving one stubborn problem: transaction costs.
Traditional payment processors charge roughly $0.30 per transaction. For ordinary consumer purchases, that's manageable. For AI agents making thousands of tiny payments per hour, it doesn't work. Micropayments become uneconomical when the fee is larger than the transaction itself. That's the bottleneck x402 is trying to remove.
USDC on Base lowers costs to fractions of a penny
Using USDC on Coinbase's Base blockchain, x402 reduces costs to fractions of a penny. That's a structural advantage, not a minor improvement. It makes high-frequency, low-value machine payments financially viable in a way conventional payment rails do not.
If AI agents are going to buy data access, trigger API calls, pay for compute, or exchange digital services continuously, they need a payment system built for volume and precision. Low-cost stablecoin payments fit that need far better than card rails or legacy processors.
Stablecoin Issuance Contract Remains Unresolved
Even with the momentum around x402 and Cloudflare's broader AI infrastructure story, the stablecoin issuance contract has not been awarded. Coinbase and Zerohash are still competing, and there is no confirmed winner or public timeline.
That leaves a key piece of the story unsettled. Still, the competition itself signals how valuable the opportunity has become. The company that secures the role would gain a meaningful foothold in a potentially important payment layer for AI agents operating across a large share of the web.
