Zillow gives away content

Officially opens API to third-party Web sites

Zillow announced today that other Web sites can now recreate the company’s functionality on their domain so that real estate agents, for example, could include detailed information from Zillow’s database of 68 million homes on their own Web sites.

Third-party consumer Web sites can incorporate Zillow’s API, which stands for Application Programming Interface, into their pages for free.

Zillow.com launched in beta, or test form, in February and includes home valuations and data on U.S. homes.
