NOTE: Fwix has consolidated this API with their other web services. View their new profile at http://www.programmableweb.com/api/fwix
With Fwix's geotagging technology, they are able to automatically index the web by latitude and longitude coordinates. The technology covers 61,000 cities in 7 countries, and is growing. The Fwix Locaion API uses Fwix's extensive database of geotagged content to provide location-based business listing data and also a way to add to the database with a writable API. Developers can build two way geo-enabled applications on the platform and get access to taxonomy, geo-tagged content, and local ads.
