Deep Tide Guide: Last week, a service marketplace designed specifically for AI Agents officially launched, and the data from the first week is out—894 Agents, 31,000 transactions, over 60 services, none with a checkout page.

This article introduces the concept of the "headless merchant": no storefront, no accounts, no sales team, just API endpoints and pay-per-call pricing, arguing one thing: the subscription-based business model is fundamentally unnecessary for AI buyers.

The full text is as follows:

Last week, a marketplace launched with over 60 services—these services are consumed not by humans, but by AI Agents.

These include:

Full-text search for all SEC filings, billed by query; CAPTCHA bypass services for Agents encountering bot verification walls; printing and mailing physical letters based on documents and addresses; image generation services from over 600 AI models via fal.ai, costing only a fraction of a cent per request.

The protocol driving this marketplace is the Machine Payment Protocol (MPP) launched by Stripe and Tempo. It allows Agents to pay with credit cards, stablecoins, or the lightning network in a single HTTP request. In the first week of launch, 894 Agents completed over 31,000 transactions in this directory, with single request prices ranging from $0.003 to $35.

None of these services have a checkout page. Their product catalog is a machine-readable schema, with pricing directly embedded in the HTTP response. Agents read the schema, send requests, make payments, and receive outputs—all in a single exchange.

A merchant once meant a storefront. Even as commerce shifted online, this model didn't change: product images, checkout pages, confirmation emails. In the e-commerce domain, "headless" means decoupling the front end from the back end. In the new Agent economy, headless means completely eliminating the front end.

This is the "headless merchant": a business without a storefront, accounts, or sales teams. Only a server, a set of API endpoints, and prices per call.

The payment infrastructure that makes all of this possible has already been launched. x402 and MPP each take different approaches, but both embed payments directly into HTTP requests. Visa's CLI tools extend card payment capabilities to endpoints. These are the foundational primitives driving headless merchants.

What Makes Headless Merchants Different

To build a traditional software business, you need a website, a checkout process, user accounts, customer service, subscription management, billing systems, and a sales team or marketing budget for customer acquisition. Headless merchants only need a usable API and a thin layer of middleware. That's the whole business.

This is important because buyers have changed. Agents arrive with tasks, budgets, and constraints. They evaluate the documentation, pricing, and reliability of endpoints. If the service meets the criteria, they pay and leave.

Payment is the certification.

Simon Taylor (@sytaylor) calls this the "intention economy": when the Agents arrive, intentions have already formed, and the merchant's only job is to fulfill it.

This disrupts how you think about building a business. Agent buyers will never see your website; they see your API documentation, pricing, and available times. A headless merchant with clear documentation and predictable pricing will almost always outperform a competitor with a pretty website but mediocre API.

Business used to happen in places: a store, a website, an app. Headless merchants move business to moments. Agents complete transactions at the exact instant they need a capability.

Shifts in Business Models

Subscription models dilute billing costs. Registering accounts, filling in credit card details, selecting plans, managing renewals—these expenses exist because it was impractical to charge a person a fraction of a cent for a single API call in the past. Agents can do it. Agents can pay a fraction of a cent per request, repeating thousands of times a day, across dozens of services, without ever creating any accounts.

This changes which businesses are feasible. A service charging $0.003 per image generated and $0.01 per webpage scraped doesn't need a sales team, doesn't need a free tier, and doesn't need to worry about user churn—because there are no subscriptions to cancel, and no relationships to maintain. It just needs to be good enough for Agents to choose it after evaluating the documentation and pricing.

If your service today relies on API keys and subscription sales, then there's a request-based version that doesn't require accounts and can be discovered by any Agent with a wallet. That version may reach customers that your subscription product cannot touch—because that customer won't even register, and Agents will simply jump to the next endpoint.

For an increasing number of service types, pay-per-use may replace subscription models. Not because subscriptions are bad, but because buyers no longer need them.

Merchants Are the Main Characters

Earlier this month, I suggested that the next wave of commerce will be built by merchants who choose stablecoins instead of choosing nothing—because traditional payment processors cannot underwrite them. Since then, the pace of infrastructure advancement has exceeded expectations. Card organizations are extending their infrastructure to Agents. New protocols have emerged that support credit cards, stablecoins, and settlement models like pay-per-session. Infrastructure is no longer a bottleneck.

What matters now are the merchants. A headless merchant with a clear API, reliable output, and pay-per-request pricing is a new type of business—such a cost structure was impossible five years ago, and such a buyer group did not exist a year ago.

The biggest opportunity in Agent commerce lies not in building the next payment infrastructure but in building those headless merchants that the infrastructure serves. The next generation of merchants will have no storefront; they will only have endpoints.
