It's forbidden by MaxMind ToS, these dudes changed the rules and forces you to abide to the new conditions when you download an update.

It's very borderline from them (at least ethically)

At the bottom of the page it credits the MaxMind GeoLite database. The GeoLite2 database is licensed as CC BY-SA 4.0. It's the GeoIP2 database that has stricter licensing.

As another reply states I publish that the source of data is indeed MaxMind. I agree ethically it doesn't quite sit right so thats why I don't charge for the service.

I didn't see anything in their ToS that would prohibit hosting an API as long as you enforce the same requirements as maxmind does?
