Step-by-step Guide to Using Zillow API

The Zillow API is applicable only to users who are interested, or part of the market's financial sector. Therefore, it is vital to state your purpose for applying for the permit to use the Zillow API.

Step 1 - Install Necessary Software On Your Device

First, open your CLI (Command Line Interface) on your device, and run the following lines of code:

pip install requests
pip install xml.etree.ElementTree

Step 2 - Setup Client-side Code

In order to work with the API, you should prepare your app's code so it can receive and process the API's response.

The code below shows a sample of a Python app.

import requests

url = "http://www.zillow.com/webservice/GetSearchResults.htm"
params = {
    "zws-id": "YOUR_ZILLOW_API_KEY",
    "address": "1600 Pennsylvania Ave NW",
    "citystatezip": "Washington, DC 20500"
}

response = requests.get(url, params=params)

Step 3 - Parse the Zillow API Response

You will receive a response once you have made the request to the Zillow API. You will then need to parse the response to use the incoming data. A sample Python code snippet that can be a base for your program would be as follows:

import xml.etree.ElementTree as ET

root = ET.fromstring(response.content)
result = root.find("response/results/result")

zpid = result.find("zpid").text
address = result.find("address/street").text
city = result.find("address/city").text
state = result.find("address/state").text
zipcode = result.find("address/zipcode").text

print(f"Zillow Property ID: {zpid}")
print(f"Address: {address}, {city}, {state} {zipcode}")
