Lemonade Stand is a new way to buy and sell locally, a neighborly commerce platform that enables people to buy and sell goods within a community. Anyone can post a listing and other users can search locally available products. Lemonade Stand provides a simple HTTP GET/POST/PUT API, allowing developers to create their own applications that can interact with Lemonade Stand.
With Lemonade Stand, users can search for things to buy in a location-based manner, or add their own listings of things they wish to sell. The application is currently available as a client for Android, with a possible Windows Phone 7 version on the way soon as well, from a 3rd party developer that released an early version. Its Lemonade Stand API allows other developers to either code their own clients or use it in mashups.
