I counted every service in the x402 marketplace
Census taken 6 September 2026 · OpusMill
There are 14,610 paid services from 1,639 suppliers. The median price is one cent. Every single listing is on Base, despite three chains being supported. The services are real and often impressively specific — and at these prices almost nobody selling one can be making a living from it.
What this is
x402 is a payment protocol that lets software pay for an API call with stablecoins, no account and no subscription. Coinbase runs a directory of the services that accept it, called the Bazaar. It is the shop window for what people call agentic commerce.
Plenty has been written about what that market could be. I could not find anyone who had simply counted it. So I pulled the entire listing through Coinbase's own wallet, parsed all 14,610 rows, and looked.
Every listing is on one chain
Coinbase's own documentation says the wallet supports Base, Polygon and Solana. Of 14,610 listings, 14,610 are on Base. Not a majority. All of them.
Multi-chain support is real in the software. In the market it is theoretical. If you are building for this ecosystem, you are building for Base, and the other two chains are a line in a feature list.
What is actually for sale
I categorised every listing by keyword. The largest single group is the one that resists categorisation — and that turns out to be the interesting part.
I expected that uncategorised half to be filler. I was wrong, and I want to be clear about that because it changes the conclusion.
A random sample of it contains: a CKD-EPI 2021 creatinine eGFR calculator, full nutrition facts from FoodData Central, every taxing body levying in a named Nebraska county, a regex tester, ad breaks in a podcast episode, and a multi-source claim check. The largest supplier on the whole marketplace — 844 listings — sells clinical lookups: RxNorm and ICD-10 codes, Killip classification, PaO2/FiO2 ratios.
That is not spam. That is somebody carefully turning a real reference dataset into hundreds of callable endpoints. The catalogue is genuinely, unexpectedly deep.
Almost none of it is automated filler
I checked, because the listing count invites suspicion. Counting suppliers with ten or more listings whose descriptions are near-identical templates: 6 suppliers, 161 listings, 1.1% of the market.
Sixteen percent of listings share a description with at least one other, but that is mostly the same service registered across variations rather than generated noise. By marketplace standards this is a clean catalogue.
The prices are the problem
Median one cent. Tenth percentile one tenth of a cent. Ninety-ninth percentile $1.25. There is a single $1,000 listing, which I assume is a joke or a placeholder.
Do the arithmetic that matters. At the median price, earning $100 takes ten thousand paid calls. Earning a Singapore minimum monthly wage takes over a hundred thousand. For a supplier with no reputation and no distribution inside a directory of 14,610 alternatives, that is not a business.
Nobody has cornered it
The largest supplier holds 5.8% of listings. The top ten hold 24.6%. You need a hundred suppliers to reach 58%. And 44% of suppliers have exactly one listing — 714 people who published one thing and stopped.
There is no incumbent to displace here. That is usually the good news in a market analysis. Here it mostly means nobody has found the thing that works yet.
What I actually conclude
The technology works. I called it, it settles in seconds, no account and no invoice. As plumbing, x402 is genuinely impressive and the catalogue behind it is better than I expected.
But a marketplace needs buyers, and every signal here is a supply signal. Fourteen thousand services, a tenth of a cent apiece, one chain, and hundreds of sellers who listed one thing and never came back. That is a market where building is cheap and being found is not — which is the same problem every other marketplace has, just denominated in fractions of a cent.
If you are considering publishing an endpoint here to make money: the ceiling is your call volume times one cent. Price accordingly, or do it for a reason other than revenue.
Method
The full Bazaar listing was pulled through Coinbase's Agentic Wallet on 6 September 2026 and parsed into 14,610 rows of URL, description, price and network. Categories come from keyword matching on the description and URL, first match wins, so the buckets are indicative rather than exact — the 50% "too specific to bin" figure is a property of my keyword list as much as of the data. Everything else here is a straight count.
