Get x402 pay-per-call endpoints built for your API

The Build Studio at CEOism builds x402 pay-per-call endpoints, so your API earns USDC per request, and you name the price for the build. No invoices, no subscription billing, no Stripe dashboard: a caller pays per call, onchain, and your endpoint responds. We have already shipped this economy twice: Agentmarket, a marketplace of pay-per-call AI agents on Polygon, and Summon, where real work gets done with just a wallet. So the plumbing, the payment flow, and the developer experience are things we have solved in production. Tell us what your API does, say the number that feels fair, and we tell you honestly what it buys. You own the endpoints, the code, and every cent they earn.

The 60-second version

Your API could charge per call in USDC. Ours already does.

We build it for you: your API earning USDC per request, no invoices, no subscriptions, just calls.

You name the price. ceoism.com/studio.

What you receive

  • Live x402-enabled endpoints on your domain
  • USDC per-call payment flow, working end to end
  • Clear developer docs so others can integrate fast
  • A pricing structure per endpoint that you control
  • Source code and full ownership

How it works

  1. 1

    Tell us what you need

    One email. Describe the thing in your own words, plain language is perfect, and say the number that feels fair to you.

  2. 2

    We build, you watch it become real

    We reply honestly with what your number gets, then we build. You see the live thing take shape, not a slide about it.

  3. 3

    You name the price

    The price you set is the price. When it ships, it is live on a real domain and it is yours: code, keys, everything.

Honest questions

What is x402, in plain terms?
It is a payment-required pattern for APIs: a caller hits your endpoint, gets asked for a small onchain payment, pays in USDC, and receives the response. It turns your API into a vending machine instead of a subscription business.
Do I need an existing API first?
No. If you only have data or a capability, we can design and build the API itself, then wrap it in x402 billing. If you already have endpoints, we add the payment layer without breaking existing users.
Who receives the payments?
Your wallet, directly. We set up the flow so funds never route through us. You hold the keys from day one and can verify every payment onchain.

Name your price on this.

Tell us what you need and the number that feels fair. We answer honestly with what that number gets.

Service 029 · three takes

The films we shoot for this one

These are the scripts we actually film, published openly. Plain text is spoken out loud. Anything in the marked panels is for the camera or the screen behind us and is never read aloud. Three takes of the same service, so we can pick the one that fits where the film is going. The first is open below. Open the other two to read them.

Take one · the empathy cutFilm 029 · 30 to 40 seconds

Your API works, it just never earns

Opens inside the worry this service answers, and takes its time. Made for someone who already has this problem in mind, so it fits this page and it fits an audience that already knows us.

Direction · do not readOpen on camera. Matter of fact.

Your API already works. People already use it. It has just never made you a single dollar.

Adding billing meant plans, invoices, a whole account system, and that was more work than the API itself. So it stayed free.

There is a simpler way now. x402 pay-per-call endpoints. Your API gets paid in USDC per request, with no subscription and no invoicing. We run this on our own endpoints, so it is not theory.

Take two · the direct cutFilm 029 · 15 to 25 seconds

Subscriptions are the wrong shape

Opens on a claim or a visible result, with the offer inside the first ten seconds. Built to be shot with a screen recording playing behind you. Made for the feed and for paid placement, where nobody was looking for us.

Screen · do not readScreen: a request hitting an endpoint, a 402 returned, payment attached, the response coming back.

Subscriptions are the wrong shape for an API.

Screen · do not readScreen: cut to the earnings view, USDC arriving per call, then the developer docs page.

We build x402 pay-per-call endpoints, so your API is paid in USDC per request. No invoices, no plans. Docs included so others integrate fast.

We run this in production on our own endpoints.

Take three · the standing offerFilm 029 · 15 to 30 seconds

Paid per call, no invoices

Names the service in the first breath instead of hiding it behind a hook, then offers to build it. It puts the barriers on the floor: you name the price, and not knowing how any of it works is our job rather than yours. It also makes the promise most people never get, that we stay with the thing until it is real. Made for someone who has been carrying this idea around for a long time and needs to hear that somebody will actually take it on.

We run this on our own endpoints, and we would put it on yours.

The plumbing is our problem, not yours.

We see it through to working, and we will build it out as far as you want it taken.
