This API is the open version of MapQuest's Search API. Nominatim is completely open-source and is used to search all named features in OpenStreetMap and a subset of other unnamed features such as pubs and hotels. Results returned in Nominatim include the feature type, address, latitude/longitude, and other OSM data fields.
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. If you think an SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
