33 worked examples — 11 platforms by 3 languages. Each one shows the authenticated call, the response that call actually returned on the day it was recorded, and the one line that pulls a field out of the envelope. Nothing to install beyond what your machine already has.

What you need, by language

curl — curl ships with macOS and most Linux distributions, and with Windows 10 and later. There is nothing to install.
Python — Standard library only — urllib and json ship with Python 3. There is nothing to pip install.
JavaScript — Node 18 or later, where fetch is global. No package to install. The same code runs in a browser, except that a browser would expose your key — call this from your server.
