When Google first launched its location-sharing service, Latitude, developers were left wondering how to access their users' data. Now, over a year later, we finally have a Latitude API.

Our API directory now includes 56 geocoding APIs. The newest is the SignalFire Postcode API. The most popular, in terms of mashups, is the geocoder API. We list 39 geocoder mashups. Below you'll find some more stats from the directory, including the entire list of geocoding APIs.
