We are developing an app named "Sliding Bar" . It's a very beautiful app where user can review there lost memories in form of pictures.
For that we are indexing all images present in user gallery and keeping a soft copy to our own database .
For this we need to trace formatted location from latitude and longitude present on every picture .
We were using APPLE own reverse geocoder , but from iOS 9 it has restricted only 50 results simultaneously .
We have used your API i.e. "http://nominatim.openstreetmap.org/reverse?format=json&lat=22.59160000&lon=88.43362500&zoom=18&addressdetails=1" and got very good as well as fast response .
But it has some limits associated . So for that we want to purchase this API , so that we can use unlimited .
Please let me know how we can achieve this .
Expecting your positive response .
