Sometimes you just need to make a REST call...

While the way we build and test online tools is evolving at impossible speeds using AI to discover data sources and build our apps, sometimes you still need to lift the hood and just make an API call.

I've been frustrated with the tools out there. Some used to be really good and just added so many features they became unwieldy. Some became corporate fronts that started breaking security rules.

So, in this age of AI, I had Claude build a REST client. This is pretty much as bare bones as you can go with a few bells and whistles.
