The OpenStreetMap Nominatim API allows developers to perform reverse geocoding operations. It searches OpenStreetMap (OSM) data by name and address to generate synthetic addresses of OSM points. Results can be returned in HTML, JSON, JSONP, or XML. Multiple companies offer their own hosted instances of Nominatum for developer use.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API.

The Geocoder Ruby SDK by Alex Reisner allows developers to perform forward and reverse geocoding, IP address geocoding, distance queries for ActiveRecord and Mongoid, and more. This SDK connects to more than 40 APIs and offers advanced configurations that allow different parameters and APIs to be used under different conditions. It also handles basic geospatial queries.
This SDK supports Ruby 2.x and JRuby as well as Rails 3, 4, and 5.
