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!
