ProgramMatek: Harnessing the Power of Zillow’s Real Estate API with Python


Zillow’s real estate APIs are revolutionizing the way developers access property information. With unparalleled access to property data and Zillow’s feature-rich add-ons like Zestimate, developers can create innovative applications in the real estate domain. Zestimate is Zillow’s intelligent estimation of a property’s value, taking into account various data points such as recent sale prices of comparable properties.

Exploring Zillow API Endpoints

Let’s take a closer look at the different API endpoints offered by Zillow, which are now available through the RapidAPI Marketplace.


Zillow’s getChart endpoint allows developers to retrieve an HTML chart containing images and property data.


The getComps endpoint provides a list of recent sales for properties that are similar to the one being queried.


With the getDeepComps endpoint, developers can access a list of recent sales for properties that closely match the queried property.


Using the getDeepSearchResults endpoint, developers can obtain detailed property information based on a specific address.


The getRegionChildren endpoint returns a list of regions that exist within a given “parent” region, as specified in the request.


If you need to retrieve property details based on a particular address, the getSearchResults endpoint will provide you with the relevant information.


Developers can use the getUpdatedPropertyDetails endpoint to obtain the latest details provided by the homeowner.


The getZestimate endpoint returns Zillow’s estimated values related to a given property (if available).

Harnessing the Power of Zillow API

The Zillow API provides powerful querying capabilities, allowing developers to retrieve information related to specific geographic areas or individual properties.

To display information about a specific property, the typical flow involves conducting a general search first, followed by a more focused query using the property’s unique identifier, known as the zpid.

RapidAPI offers example code snippets that illustrate this process. For instance, you can start by searching for a known address. Here’s an example code snippet:

import requests

url = ""

payload = "rentzestimate=true&rentzestimate=false&zws-id=<YOUR ZILLOW ID>&citystatezip=97525&address=583-N-5th-Ave-Gold-Hill-OR"

headers = {
    'x-rapidapi-host': "",
    'x-rapidapi-key': "YOUR RAPID API KEY",
    'content-type': "application/x-www-form-urlencoded"

response = requests.request("POST", url, data=payload, headers=headers)


Once you receive a response from Zillow, you can further utilize their API to request an HTML chart containing images and data about the property. Here’s an example of the code snippet:

import requests

url = ""

payload = "chartDuration=1year&chartDuration=5years&chartDuration=10years&zpid=48327876&unit-type=dollar&zws-id=<YOUR ZILLOW ID>"

headers = {
    'x-rapidapi-host': "",
    'x-rapidapi-key': "YOUR RAPID API KEY",
    'content-type': "application/x-www-form-urlencoded"

response = requests.request("POST", url, data=payload, headers=headers)


Zillow’s API responses are in XML format, but you can easily convert the returned data to JSON for easier consumption. Here’s an example of a Flask app that demonstrates this conversion:

from flask import Flask, request, jsonify
import requests
from lxml import etree

app = Flask(__name__)

YOUR_RAPID_API_KEY = '<Your Rapid Api Key>'
YOUR_ZILLOW_ZWS_ID = '<Your Zillow ID>'

def index():
    return """
    <form action="/get-chart" method="post">
    <p><input type=text name=zpid placeholder=zpid>
    <p><input type=submit value="Get Chart">

@app.route('/get-chart', methods=['POST'])
def get_chart():
    zpid = request.form.get('zpid')
    url = ""

    payload = "chartDuration=1year&chartDuration=5years&chartDuration=10years&zpid={0}&unit-type=dollar&zws-id={1}".format(zpid, YOUR_ZILLOW_ZWS_ID)

    headers = {
        'x-rapidapi-host': "",
        'x-rapidapi-key': YOUR_RAPID_API_KEY,
        'content-type': "application/x-www-form-urlencoded"

    response =, data=payload, headers=headers)
    root = etree.XML(response.content)

    data = {}
    for element in root.iter():
        data[element.tag] = element.text

    return jsonify(data)

if __name__ == '__main__':
