That's just GUIs being easier to use than CLIs for most people. After all, that's why Postman got popular - it's a GUI to do curl without the CLI! Or Handbrake to avoid using ffmpeg. Or various "paint" applications to rotate images instead of using imagemagik.

The problem is that Postman decided to want to be a business and took VC money.

I know lot of bits with curl. But I find it always a pain to use. Fine for when you do scripting but I find command line pretty painful overall. So I understand want to use some other tool with better ergonomics.

I wrote a lot of python. Whenever I was working with an API, I'd just spin up a jupyter notebook and write out the calls I wanted to try out in a python notebook, once I had everything working, it was just a copy paste job into the codebase.

Using some kind of dedicated tool like postman always felt like a literal step backwards.

10 years ago I totally get that but these days there's plugins built into every IDE that can smooth over the annoyances of testing an API via curl without having to invoke paying for Postman and dealing with all of its nonsense.

Of course now that I said that today I'd probably just have Claude hit the API for me, or build a dashboard to test it, I really don't know how Postman continues to exist.
