We have beta SDK's available for Python[0] and Ruby[1]. There are free test listings available if you're interested in trying it out (no signup required).

My brother and I co-founded SimplyRETS earlier this year to solve the real estate industry's archaic data problem. We built a modern, RESTful API in Haskell that normalizes MLS data and makes it easier for developers to build websites and applications.

We'd love to hear your thoughts and feedback!
