Waytag is a geolocation service. Waytag allows users to create a "waytag" with the address and GPS coordinates for letting people know where they should meet. Individuals and businesses can create Waytags, and users can also search for Waytags.
The Waytag API allows developers to access and integrate the functionality of Waytag with other applications and to create new applications. Public documentation is not available; interested developers should register here http://devzone.waytag.com for API access.
