02 How it works

From idea
to live API

Four steps from problem to recurring revenue. We do everything ourselves — no clients, no hand-offs, just us building APIs the world can use.

Ship
it.
01 We identify a problem
+
We research developer pain points and market gaps to find API opportunities worth building. No guessing — we validate demand before writing a line of code.
02 We build the API
+
We design and develop production-grade REST APIs with FastAPI, full OpenAPI docs, authentication, rate limiting, and tiered plans — ready for real traffic from day one.
03 We publish it
+
We list the API on RapidAPI and other marketplaces, writing SEO-optimized descriptions, code samples, and docs so developers can find and integrate it fast.
04 Developers subscribe
+
Developers worldwide discover, test, and subscribe to our APIs. Revenue is automatic and recurring — no sales calls, no client management.
03 The studio

We are a small
independent
studio.

StackMint builds and publishes its own APIs. No client work. We pick a problem, build the solution, ship it to RapidAPI, and let developers around the world use it.

ComplianceWatch is our first. More are coming.
