Scraper for zillow.com using API

I currently use a scraper for [login to view URL](perl) but since there are often minor changes in the website, changes need to be made to the script often. I want a scraper which gives me all the same data as my current scraper, but comes from zillow's API. That way I do not have all the problems of constantly fixing the scraper. There is one more thing that the scraper does which does not come from zillow. it comes from here [login to view URL] the amount in the redemption column should only count the defaulted secured bills. ignore the unsecured bills. I can send you a sample of input and output data.
