Query Apple's FindMy network with Python

It’s interesting, because it could allow you to log location over time. Generally, I can only see peoples location when I open the app, but this would allow me to ping every 30 minutes and create a very long log that I could technically create manually, but would be quite a bit of work.

You don't need to do that, the API will happily return the last N days of location pings.

This, indeed. Quick addition: Apple only stores locations for up to 7 days, so I would recommend running it once per day or so if you don't need live data. If you do, be careful not to request too often (sub-30 mins) if you value your account dearly.
