It's interesting and I like it. It does seem to be rather opinionated without saying so. The PHP example requires an http library I hadn't heard of (rmccue/requests). Copy/paste of that code doesn't work unless you know how to find and install that library. The related tool they reference, however, does work using the PHP curl library.
I presume they were trying to keep the code to 4 lines or so. The curl library in PHP is rather verbose and requires 5 to 8 lines (depending on if you try to catch the error).
At the time we were using that particular library heavily at WizeHire. I had built the tool for personal convenience. rmccue/requests was likely one of the first "generators".
I expect that we'd accept a PR for PHP curl library implementation. Having a non-third-party option would be valuable.
