davemachado/public-api ? reverse-engineered prompt

Build me a small public API service for the public APIs project.

I want a simple web app that lets people browse all the APIs in the catalog, search and filter them by things like title, description, auth type, HTTPS support, CORS support, and category, and also get one random API entry. It should also have a page or endpoint that returns the list of categories, plus a basic health check so I can tell if the service is running.

Please make it work with no login, allow CORS, and serve everything over HTTPS friendly responses. Keep it clean and reliable, since this is meant to be a public service people can use from other apps. If you need to look up any current library or framework docs online, go ahead.
