I work at IPinfo. We offer unlimited free requests through the IPinfo Lite API. By unlimited, I mean millions of requests per day. The free API provides country and ASN data.

As far as I know, GeoLite2 does not have city-level data for a large number of IP addresses. Even when it does, the city-level accuracy can be quite poor.

So I'd suggest just using our API and pointing to the capital city. That would also remove the need to pay for a VM.

Business oppotunity --- provide this as a service for a more reasonable fee.
