Bing Maps Java SDK provides a Java wrapper to Microsoft's Bing Maps API. This allows developers to access the API's methods for searching for points of interest, getting driving directions, matching addresses to the map, and more. This project is currently open for adoption as the creator no longer has time to maintain it.
The Health team at Bing used public data to create a Health Map application (requires Silverlight) that lets users visualize a number of health indicators, such as obesity and premature births, by U.S. county.
MapQuest has launched another API on top of OpenStreetMap (OSM), the Wiki-like editable map of the world. The new search service provides geographic search results for any data added to OSM, such as streets or landmarks. Of note, the MapQuest API provides the service without any API Key requirements or rate limiting.
