RockstarApps has built the first Facebook application (App) to publish Zestimate values using the Zillow API. Keep Up w/ the Jones is a simple App — just enter your address to keep track of your Zestimate and share it with your friends (note: you can chose to make your Zestimate private). Once you’ve added the App, you can also see your friends’ Zestimates (if they’re shared.) Zestimate values are ranked from highest to lowest; hence the App’s catchy title. It includes an innovative graphic that illustrates both the Zestimate value and the value range (see below).
Give it a whirl and please Digg it if you think it’s cool. If you know of other Apps that use the Zillow API please say so (in the comments.)
