If this repo gives you a build idea, saves you research time, or helps you spot a better API opportunity, give it a star.
That makes it easier for more builders to find it, and it gives the repo social proof as the playbook library grows.
Most API collections are giant dumps.
They tell you what exists, but not:
- what to build
- who will pay for it
- what the MVP should be
- how quickly you can launch
- how to turn an API into recurring revenue
This repo is built to answer those questions fast.

Some API links in this repo preserve affiliate tracking from the original source material. That does not change the selection standard here: the bar is still whether an API can credibly support a useful business.
The original cloned mega-list content still exists in archive/legacy-api-dump for traceability and future mining, but the main experience is now curated.
