I am interested in getting aggregate dollar values for listings/sales on Zillow (for the whole country summed together, for example). Unfortunately, Zillow's data page seems to only show the "ZHVI", an index value, not a total dollar value. Is there any way to get the total dollar value?
This is not an open data set at this time. However the API may satisfy your needs:
I don't see how this helps. I see no API call for requesting aggregate data. Feb 16, 2015 at 14:10
I just said the API may satisfy your needs. I don't know. API calls would help if you really wanted the value. You would have to make many API calls and aggregate them yourself if that was the route you wanted to take. Are you looking for zillow specific data, or real estate (MLS) data in general?

If even thought of trying to query every house in Zillow, the company would put out a contract on me. Feb 16, 2015 at 14:53
