Plunk APIs for Developers

Overview

Plunk currently provides the following APIs for Developers to integrate Plunk's unique insights into their applications:

Home Value API: real-time valuation for homes in the U.S.
Market Insights API: real-time and historical real estate market trends

Home Value API

The Home Value API provides the current real-time estimated value for a given parcel.

Full API documentation is available here: Plunk Home Value API Docs

One use case for this API is to display the estimated value on a home’s real estate listing page, as below, where we show the value of the home “ticking” according to its rate of change:

Note:
We can also provide sample web UI code (HTML, CSS, JavaScript) that renders the Plunk Home Value as illustrated here, including the option to animate the Ticker behavior.

Market Insights API

The Market Insights API provides access to dynamic real estate market statistics, including a time series containing up to three years of historical values. Initially, statistics are reported at weekly granularity, and at the ZIP code level.

Full API documentation is available here: Plunk Market Insights API Docs

The following six market statistics are available through this API, along with their 90-day moving averages:

Sale vs List Price—a measure of the magnitude by which homes are selling above or below list price
Median List Price—the average asking price for homes on the market
Price Per Sq Fta measure of the typical price of a home, normalized by the size of the home
Inventory—a measure of the active supply of homes on the market
Days of Inventory—a measure of how fast the existing on-market homes would last, presuming:
(i) no more listings are added; and (ii) the current rate at which homes are selling is stable
Median Days on Market—a measure of how long homes typically stay on the market

One use case for this API is to display the trends impacting a given home’s value on its real estate listing page, as in the following screenshot, where we show the six key Market Insights and their 90-day moving averages:
