Zillow – API and Mobile Feature
The Zillow API is still being developed, although they’ve given some details on the Zillow blog. Yahoo is already using the API, as well as this test site from a company that build sites for agents.
The mobile feature allows you to obtain the value of a house by email/sms. To use it, text or email a home address to z@labs.zillow.com. I agree with SocketSite – Zillow Mobile you no longer have to wait until you get home from a dinner party to figure out how much your host’s house is worth. Another use, of course, is to check home values in a neighborhood when you visit an open house.
