Zillow Crawl API: Real Estate Data Interface

Zillow Crawler Crashed by Anti-crawl? Try this wildcard.

Recently, a lot of friends doing real estate analysis have complained to me that Zillow's CAPTCHA is getting more and more perverted, and the IP is blocked just after grabbing two pages of data. Last month I helped my friend's company to do data collection, and found that it was impossible to play with conventional means, and finally relied on proxy IP to break the game. Today, I will share some practical experience with you and teach you how to use ipipgo's proxy service to glean data in a stable manner.

How wild is Zillow's anti-climbing routine?

This platform's anti-crawl mechanism is really not a vegetarian, and I've compiled three of their most common tricks:
1. IP Frequency Monitoring: The same IP access more than 5 times in a row, directly to you pinch the line!
2. fingerprint recognitionBrowser fingerprinting, request header characteristics, mouse tracking, and more!
3. Dynamic Loading Pitfalls: The page data is loaded seven or eight times, with honeypot links sandwiched in between

The most pitiful thing about them is theirIP Reputation LibraryThe IP segments of common server rooms on the market have long been memorized in a small book. Once I used a certain proxy and it triggered wind control just after startup, then I switched to ipipgo's residential proxy to fix it.

The right way to open a proxy IP

You have to look at three hard indicators to choose an agency service:
- Survival time: short-acting agents (3-5 minutes) are safer than long-acting ones
- Type of network: must be selectedPure Residential IPThe data center IPs are basically given for nothing.
- Geographic location: it is recommended to choose the local IP of the target site, for example, to climb the U.S. listings, use the U.S. West residential IP

Here must be an encore of ipipgo'sDynamic residential agent poolI've never triggered a CAPTCHA with them, and their IPs are all real home broadband, switching automatically with each request. The key is that the price is more real than the counterparts, new users can also get 3G traffic trial.

import requests
from itertools import cycle

proxies = cycle(ipipgo.get_proxy_list()) auto-rotate proxies

for page in range(1, 100): current_proxy = next(proxies)
    current_proxy = next(proxies)
    try.
        response = requests.get(
            
            proxies={'http': current_proxy, 'https': current_proxy}, headers={'User-Agent': 'Mozilla/5.0')
            headers={'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36...'}
        )
         Processing data logic...
    except Exception as e.
        print(f "Flipped with {current_proxy}, automatically cut next")

A practical guide to avoiding the pit

Follow these five steps below to ensure you get a solid grip on your data:
1. Request for rhythmic control: Stop for 10-15 seconds for every 3 pages to mimic real people browsing.
2. Header disguise: don't use the default UA of requests, go to the real browser and grab the request header
3. Failure Retry Mechanism: Auto-sleep for 1 minute when 429 status code is encountered
4. data validation: check if the returned result contains honeypot features (e.g. abnormally low prices)
5. Timed change of exit IP: It is recommended that IP segments be completely changed every 20 minutes

Once I was lazy and did not set the request interval, the results of ipipgo background shows 10 minutes with more than 200 IP. later added random delay, traffic consumption directly down 60%, but the data is more stable.

Frequently Asked Questions QA

Q: Why did you use a proxy and still get banned?
A: 80% of them are using data center proxy, or the request header is not well disguised. Switch to ipipgo's residential proxy and remember to bring a different browser fingerprint for each request!

Q: Do I need to maintain my own IP pool?
A: No need at all! ipipgo's API automatically eliminates failed IPs and also intelligently allocates resources based on the type of business. I've set up a financial-grade cleaning policy, and I've been using it for half a year without any rollovers!

Q: How fast can the crawl be?
A: measured single-threaded per hour can catch 800-1000 data, with distributed crawler + ipipgo 10 concurrent channels, day picking millions of data no problem!

Q: What should I do if I encounter a CAPTCHA?
A: ipipgo'sSmart CAPTCHA SolutionsCan automatically handle the verification of 90%, the rest of the difficult to get to go manual coding channel, the success rate of 99%

Tell the truth.

Engage in data collection this line, the spell is the quality of resources. I compared more than a dozen proxy services, and finally selected ipipgo on two points: one is their IP pool updated daily 20%, and the second is the technical support response fast. Once encountered technical problems at three o'clock in the morning, the work order seconds back, which is really rare in the industry.

Lastly, I'd like to remind newbies not to buy junk proxies on the cheap. Last time, there is a buddy with a free agent to climb Zillow, the result of the account was blocked not to say, but also ate a lawyer's letter. Professional things to professional tools, ipipgo is now doing activities, registration code [ZILLOW666] can be discounted 20%, they go to the official website to see it.
