So, I built an API that only reads heavily indexed sqlite databases for cell tower locations and ips. And I also built a feeder that turns OpenCellID data (for calculating the position in relation to the cell towers) and DbIp data (for the fallback) into a local database for the API, no outside connections and no wifi beacons as of the moment, because no one gives that information anymore it seems, if anyone knows where to find the dead mozilla data, i would like to add that too.

I based the API on this so microg or any app can just plug into it and anyone can host their own location services. Also, there will be a about endpoint to give information about the instance, databases used (proper atribution, etc) and the codebase, as well as the AGPLv3 license.

I'm going to release the source (shitty) code as soon as I test the basic things, if it works in real life, etc, or if I would need to ditch the weighted centroid aspect and put in a optimization step to get better results in respect to the distance to the towers.

In this aspect, I'm seeking testers hahah.
