I know "negative" comments are discouraged for Show HN, but seriously who is using this type of thing? I'm really not sure I understand the point of things like this, besides "make every possible library/unix tool a service". What's next, "sprintf as a service"? Maybe just "println as a service". You make a request, and it returns the same string with "\n" appended. The MaxMind GeoLite database will give you quite a lot more information than this does, with a single call to the library, and can be delivered as part of your main page response if necessary. The MaxMind GeoLite database also isn't reliant on CloudFlare to work.
