APIScout — find, filter & test free public APIs

The problem

The public-apis list is great but static: you can't test an endpoint, can't find the no-auth + CORS-friendly ones, and it claims HTTPS support it never actually verified.

The build

A searchable frontend for public-apis with a live in-browser "try it" playground, a no-auth + CORS filter, real categories (Animals, Anime, Weather…) as browsable tiles, popularity ranking, and a build-time verifier that marks HTTPS as verified vs merely claimed. 1,500+ APIs.

Stack & choices

  • Next.js · TypeScriptStatic directory + one SSRF-hardened proxy route for the playground
  • Tailwind CSSLight "dev playground" design with an animated hero
  • VercelHosting

Process notes

  1. 1

    A build-time pipeline verifies HTTPS and scrapes GitHub activity — claims are checked, not asserted.

  2. 2

    Live "try it" calls run client-side for CORS APIs, else via a hardened proxy.

  3. 3

    Free, open source, Ko-fi link — stars welcome.
