Good news: Real estate-relevant API's keep coming

Mashable reported today that HopStop, a site that tells users how to get from Point A to Point B using mass transit, has released an API.

This adds to a slowly growing list of free real estate or real estate-relevant API’s. Google Maps is the granddaddy of API’s in our space, but there’s more out there now for real estate web developers to work with.

For brokers, online real estate companies, MLS organizations or anyone looking to create a richer online real estate experience, these can be invaluable resources.

And – let me say it again — they are free.

Here’s list of API’s I’ve seen put to good use, with links to their documentation. I’m sure I am missing something – so please point that out.

Yelp: Local business reviews

Walkscore: Determine the “walkability” of any listing or neighborhood

Education.com: Comprehensive school data

Zillow: Home values, demographics, market trends and more

Cyberhomes: Home values, sold data and market trends
