Yahoo! Maps Web Services - Geocoding API
Finding Latitudes and Longitudes
The Geocoding Web Service allows you to find the specific latitude and longitude for an address. You can use this service to geocode your points in advance or forego it altogether with built-in geocoding in our AJAX and Flash APIs.
This API has been deprecated (that is, no longer recommended for use by new developers). A new geocoding API called Yahoo! PlaceFinder is now available and provides more features than this API, including reverse geocoding (translating coordinates into street addresses) and WOEID support. Current developers using this API are encouraged to migrate to PlaceFinder.
