Grabbing Zillow Data: A Guide to Capturing Home Prices

Why do I have to use a proxy IP to capture Zillow home price data?

If you've done data capture, you know that Zillow is a very strict site. Let's take a real example: last year, a friend who did real estate analysis used his own server to grab 3 days in a row, and as a result, the IP of the whole server room was blacked out, which delayed the progress of the project. At this time, if you would use a proxy IP, such asDynamic residential IP for ipipgo, rotating access to different addresses won't trigger a ban at all.

What is the difference between a regular agent and a premium agent?

Proxy IP on the market is divided into three, six, nine and so on, here to draw a key comparison:

Special reminder:ipipgo's residential proxy comes with browser fingerprint masqueradingWhen you catch Zillow, you don't even need to change the User-Agent, the system automatically simulates the behavior of real users.

Hands-on teaching you to match the proxy to catch the data

Here's a real life example in Python, let's say we want to capture listing prices:

import requests
from random import choice

 List of proxies from ipipgo
proxies = [
    "http://user:pass@gateway.ipipgo.com:8001",
    "http://user:pass@gateway.ipipgo.com:8002"
]

url = "https://www.zillow.com/homedetails/123-Main-St"
headers = {
    "Accept-Language": "en-US,en;q=0.9", "Referer":"
    "Referer": "https://www.google.com/"
}

try: response = requests.get()
    response = requests.get(
        url,
        proxies={"http": choice(proxies)},
        headers=headers,
        timeout=8
    )
    print(response.text)
except Exception as e.
    print(f "Crawl error, try another IP: {str(e)}")

Note the two tasty operations in this code: 1. randomly selecting proxy IPs each time 2. bringing sensible language and source parameters, both of which are key to avoiding being banned.

Must-know anti-blocking tips for capturing data

- Don't scratch like a chicken.: set a random delay of 3-5 seconds, just use time.sleep()
- Don't always focus on one area to catch the listings, ipipgo backstage can specify different state IP rotation collection
- Don't fight with CAPTCHA, change IP and try again.
- Update the User-Agent library weekly, don't let the website see the pattern

QA time: the pitfalls you may have encountered

Q: I used a proxy IP and still got blocked?
A: Check if you are using a transparent proxy, be sure to use ipipgo's high stash of proxies, packages with automatic IP rotation function

Q: What should I do if I can't catch all the data?
A: 80% is triggered by anti-climbing, try these two programs: 1. reduce the amount of concurrency 2. contact ipipgo customer service to open a whitelist IP segment

Q: How to judge the proxy IP quality?
A: Take 10 IPs to visit https://httpbin.org/ip to see if the returned IPs and the actual ones are the same, the success rate is lower than 90% hurry to change the provider!
