I should clarify that I was looking for an "offline" API/library that I can use against a local copy of the Lite database, but this is great stuff too.
I thought maxmind has some kind of terms change that forced account signup and some other issues 'because of some privacy law' like gdpr - maybe the Cali one?
So it has ruined my second favorite wordpress security plugin - and MaxMind not really usable like it once was (?)
