Software for mass compiling home estimated values

[Graham Gochneaur]

Hey guys, I was wondering if anyone knows of any software that will allow you to input a CSV file of addresses of homes and automatically output that file back with estimated home values?  I'm looking for one that can handle at least 200 at a time, and gives reliable estimates back by utilizing the api feeds from sites like zillow, redfin, trulia, etc.

Thanks in advance!
