Get your API designed and shipped, ready to be built on
The Build Studio designs and ships APIs: clean endpoints other builders can pay for and build on, at a price you name. Your data could be earning rent, and an API is how. We design the endpoints around real use cases, document them so a stranger can integrate in an afternoon, add keys and rate limits, and deploy on infrastructure that stays up. If you want the API to earn directly, we can wire in billing, including pay-per-call USDC via x402, which we already run in production on AgentMarket, one of the studio's 47 live apps. Tell us what your API should serve and to whom, say a fair number, and we will tell you honestly what it buys.

Honest questions
- How do I charge people for using my API?
- Subscriptions with keys and tiers, metered billing, or pay-per-call in USDC through x402, which needs no invoices at all. We run the x402 model live already, and we will recommend whichever fits your buyers.
- What makes an API good rather than just functional?
- Predictable naming, honest errors, versioning that will not break integrators, and docs written for the person integrating, not the person who built it. Builders can feel the difference in the first ten minutes, and they stay or leave on it.
- Can you build the API on top of my existing app or database?
- Yes, that is the most common case. We read what you have, design endpoints over it without disturbing the app, and keep the data layer safe behind proper access controls.
