You can deploy it and run it for free on Google app engine. Only works for requests that come from the client directly. So you can't ask for a specific IP.
What is the data supposed to represent? Given an IP, I get back some indication of location. Is this
(a) The location of the user who uses this IP at the moment?
(b) The location of the device that is assigned this global IP?
(c) The location of the switch/router at the ISP that is directly connected to the device with the IP?
(d) The headquarters location of the organization that registered the IP block.
(e) Some other location we can't describe.
(f) One of the other answers, but at some time in the past.
These are not all the same location, and not necessarily the same country. Think about people using phones, on airplanes, at sea, in the desert using starlink, corporations using internal networks to get to an ISP POP in another country.

Nothing on there about how or why I would trust this information over all the other free sources I can choose from.
Tell me more about your collection process...

would be nice if this also served a static "api" of json documents for responses to queries, so that we don't have to install additional mmdb modules
