Tuesday Night: median listing prices and slight data format change

Hi everyone,

We are going to be releasing an update to the API on Tuesday evening, which includes median prices for our listings. I wanted to give all of the API developers a heads up so everyone is expecting the change. Specifically, we are taking data calls that return XML that looks like something like this:

<listingStats>
  <listingsStat>
    <weekEndingDate>2007-02-10</weekEndingDate>
      <avgListingValue>
        <subcategory>
          <type>All Properties</type>
          <averageListingPrice>1724582</averageListingPrice>
          <numberOfProperties>2883</numberOfProperties>
        </subcategory>
        <subcategory>
          <type>1 Bedroom Properties</type>
          <averageListingPrice>729525</averageListingPrice>
          <numberOfProperties>1080</numberOfProperties>
        </subcategory>
        ...
      </avgListingValue>
    </listingsStat>
  </listingStats>
</TruliaStats>

...and changing it to look like this:

<listingStats>
  <listingStat>
    <weekEndingDate>2007-02-10</weekEndingDate>
    <listingPrice>
      <subcategory>
        <type>All Properties</type>
        <numberOfProperties>2883</numberOfProperties>
        <medianListingPrice>836333</medianListingPrice>
        <averageListingPrice>1724582</averageListingPrice>
      </subcategory>
      <subcategory>
        <type>1 Bedroom Properties</type>
        <numberOfProperties>1080</numberOfProperties>
        <medianListingPrice>651408</medianListingPrice>
        <averageListingPrice>729525</averageListingPrice>
      </subcategory>
    </listingPrice>
  </listingStat>
</listingStats>

As always, feel free to email us with and questions or suggestions about this change or any others you would like to see. Thanks!

Big boost in Trulia API Listing Volume Data Coming Your Way

As a result of a partnership with Realogy Corporation, the global leader in real estate franchasing with more then 500,000 affiliate real estate listings, over the next few weeks you should see a significant increase in listing volume data that is made available through the Trulia API. You should expect to see a large spike in the volume numbers that are in API in the next few weeks.

Specifically all property listings that currently reside on the a CENTURY 21®, Coldwell Banker®, and ERA® brand Web sites have been provided to Trulia.

You can read more about the partnership on our blog.

Cheers,

Welcome to the Trulia API!

Welcome to the Trulia API!

For the last few weeks we've worked long hours to develop an API that gives you access to Trulia data, including search traffic and real estate price trends for any state, county, city, ZIP, or neighborhood in the US. You can also look up longitude and latitude information for any of these locations.

You can use the Trulia API data to build a host of applications, from predicting future market prices based on historical market pricing and Trulia traffic trends to building your very own heatmap!

Check out the application gallery to see some examples built by a few engineers at Trulia during a 24-hour hackfest held in our office. If you build something cool, let us know and we'll add your app to the gallery to show it off to the world!

To learn more about the data made available by the Trulia API, you can read the documentation. If you have any questions or find anything buggy/difficult or use, feel free to send me email at developers@trulia.com.

Finally, if you aren’t a developer, or if you just want to read a summary of the “what” and “why” of the open Trulia API, check out our post on the Trulia Blog.
