Now, businesses are selling to those agents. With ZeroClick-powered Agent Storefronts, they offer services like inference, market data, image generation, publisher content, and more, priced per request and paid in seconds. Today, we're sharing how we're working with [Coinbase](https://www.coinbase.com), the authors of x402, to bring the next wave of businesses online. If you've watched your site's traffic mix change over the past year, you already know that AI agents are becoming the web's primary actors. They research products, compare prices, make buying decisions, and complete purchases on behalf of the people and companies they work for. Over 50% of traffic on the internet today is not human. The traditional infrastructure for selling to humans is not optimized for selling to agents. To win with agents, businesses need Agent Storefronts: a hub where agents can access a business's full corpus of information in clean, machine-readable formats, with support for agent-friendly payment methods like x402, tokenized cards, and more. ## Agents are using x402 x402 is an open, neutral standard for internet-native payments. It makes payments possible between clients and servers, creating economies that power agentic payments at scale. When Coinbase introduced [x402](https://www.x402.org) in 2025, it picked up the web's oldest unfinished idea: HTTP status code 402, "Payment Required," reserved since the 1990s and never put to work. With x402, Coinbase turned it into a functioning payment flow. The flow works in two round trips: 1. An agent makes a request to a service. 2. The service answers with a 402 and a price. 3. The agent pays in USDC on Base. 4. The request retries with proof of payment, then completes. No account, no API key, no subscription required. Agents are already spending millions of dollars via x402. In the last 30 days alone, there were over 14 million agentic transactions. We expect that number to increase by orders of magnitude in the coming months and years. Selling to agents is not some future bet — it is a current necessity. The businesses that lean into this will thrive, while those that don't risk being ignored by the internet's next big customer. ## What agents can buy right now Agents can buy hundreds of services via x402 today. Companies like [Exa](https://exa.ai/), [Parallel](https://parallel.ai/), and [Browserbase](https://www.browserbase.com/) are already live with agent-friendly x402 offerings. As the market grows, startups and incumbents alike are increasingly leaning in. Below is a sampling of businesses that have recently launched Agent Storefronts with ZeroClick. Each is live today, selling real services to agents over x402: - **[DeepAI](https://zeroclick.ai/blog/deepai-ai-image-tools-any-agent-can-buy)** — image tools. Six services ranging from image generation to upscaling, including an HD image for one cent. - **[ActionLayer](https://zeroclick.ai/blog/actionlayer-real-world-tasks-any-agent-can-buy)** — real-world tasks. An asynchronous task API where agents hand off jobs that still need a human touch or real-world engagement, within set budgets and guardrails. - **[ZeroGPU](https://zeroclick.ai/blog/zerogpu-specialized-inference-any-agent-can-buy)** — specialized inference. Small, fast models metered per call, so an agent can match the model to the task and pay for exactly the tokens it uses. - **[Affiliate.com](https://zeroclick.ai/blog/affiliate-com-commerce-data-any-agent-can-buy)** — commerce data. Product search, merchant lookups, and identifier conversion across more than a billion normalized products, at two cents per request. - **[Dappier](https://zeroclick.ai/blog/dappier-premium-publisher-data-any-agent-can-buy)** — publisher data. Licensed, real-time content from trusted media brands, so agents can buy answers from the premium web instead of scraping it. - **[x402stock](https://zeroclick.ai/blog/x402stock-market-data-built-for-the-agentic-web)** — market data. 140 paid endpoints across equities, options, forex, crypto, and macro, starting at one cent. - **[DubbleBlack](https://zeroclick.ai/blog/dubbleblack-commerce-evidence-any-agent-can-buy)** — commerce evidence. Behavioral purchase intelligence based on real commerce data. When the data is thin, it returns "insufficient evidence" rather than inventing an answer. - **[Bytemine](https://bytemine.ai)** — B2B data. Contact and company records at under a penny each. Track funding, hiring, and intent signals; find contacts and companies; enrich lists; and more. 135M+ contacts, 80M+ verified mobiles, and 10M+ companies. ## It pays to be early Companies that translate their business to an agent-friendly format are quickly recognized for doing so. There is an advantage to being early. Try searching "Can agents buy from [company]". Businesses with ZeroClick-powered Agent Storefronts — DeepAI, Bytemine, and others — already have a strong agent-friendly reputation. That advantage compounds with time. Nearly all companies choose to run their storefront on their own domain: [agents.x402stock.xyz](https://agents.x402stock.xyz/llms.txt), [agents.bytemine.ai](https://agents.bytemine.ai/llms.txt), [agents.zerogpu.ai](https://agents.zerogpu.ai/llms.txt). Selling to agents is becoming a primary growth channel. ## How Coinbase and ZeroClick work together Coinbase created the x402 protocol. ZeroClick creates Agent Storefronts that use it. We are working together to grow the agentic commerce ecosystem and help businesses sell to agents. Every new Agent Storefront we stand up represents another service that is available to agents and purchasable via x402. > "ZeroClick is making it easier for merchants to build and manage headless stablecoin payment infrastructure so they can serve paying agents. By bringing x402 and the CDP facilitator into merchant workflows, ZeroClick is expanding adoption of USDC on Base and helping turn agent commerce into an everyday reality." > > — Kevin Leffew, AI Partnerships, Coinbase Developer Platform Supporting x402 in our Agent Storefronts was a natural decision. The protocol was authored by one of the most trusted names in the industry, is now governed in the open via the x402 and Linux Foundations, and is backed by Google, Visa, Mastercard, AWS, Shopify, and more. x402 is an open, neutral standard for internet-native payments. ## How Agent Storefronts work ZeroClick Agent Storefronts turn any API, SaaS, or product offering into an agent-purchasable service, with support for x402, machine-readable documentation, agent transaction analytics, and agent-optimized payment methods. Every seller gets a hosted pay URL (for example, agents.company.com). The pay URL is a machine-readable storefront: agents read it to find your services, plans, and prices, then transact with your API through it. **Step 1. An agent calls your pay URL.** An AI agent discovers your storefront, picks a plan, and calls your service through the pay URL using x402 or MPP. **Step 2. ZeroClick authenticates and charges.** ZeroClick resolves the agent's identity, handles the payment challenge, then signs the request and forwards it to your API. If an agent has no wallet, ZeroClick can create one on the spot or generate a card payment link. Your storefront can do business with an agent whether they use stablecoins or fiat. **Step 3. Your API serves the request.** Your API verifies the request signature, checks the agent's allowance, and returns the result. **Step 4. You get paid.** Funds settle directly to your Stripe account. ZeroClick records the usage and the transaction for analytics: which agents bought, which payment rails they used, and how each service converted. **What ZeroClick handles, and what you build** ZeroClick operates the agent-facing side: the storefront, payment challenges, wallet and identity resolution, payment verification and settlement, request signing, usage recording, and transaction analytics. You add one thing to your API: a billing guard. On each forwarded request, your backend verifies ZeroClick's signature, checks the agent's allowance, does the work, and reports what was used. The [seller SDKs](https://docs.zeroclick.ai/sdks/overview) for TypeScript, Python, Go, and Ruby implement the guard. The [REST walkthrough](https://docs.zeroclick.ai/integrate/rest-walkthrough) covers doing it without an SDK. Once your Agent Storefront is live, ZeroClick registers it across major agent indexes including Coinbase's [agentic.market](https://agentic.market/) and [zero.xyz](https://www.zero.xyz/), so your services appear wherever agents search. ## Get started If you're building agents, point them at any storefront above and your agent can take it from there.
