FYI, server-side APIs don't require premium accounts. :)
I'm pretty sure it's the same mechanism used for mobile/app non-browser tracking.
how can GA correlate between site then ? The server-side does not have access to my GA cookie. Browser fingerprinting ?

Yes, cookies are outdated and just a fallback. Also, unless you never go to a google-owned domain name, you'll be cookied regardless.
You can also just host the ga.js file yourself. Or run a reverse proxy or any of a dozen other methods to collect data and pass it to GA. Using the standard 3rd party tag is just for convenience.
