eBay Web Crawl: eBay Data Proxy Capture Solution

Why do eBay crawls always fail? You may have stepped into these three potholes

Folks who have engaged in eBay data crawling know that the anti-climbing of this platform is like cowhide candy that can't be shaken off. Obviously, yesterday you can run the script, today suddenly 403, gas not popularity? In fact, eighty percent of yourIP addresses are being targeted.. Don't rush to smash the keyboard, let's disassemble the problem by hand.

Demystifying eBay's Anti-Crawl Triple Axe

1. IP Frequency Monitoring: Continuous access to the same IP, more than 5 times within 30 seconds directly shut down the small black room
2. Behavioral Fingerprinting: Mouse tracks, page dwell times, all these details are exposed
3. CAPTCHA raid: Suddenly the image validation pops up, and the script goes to sleep on the spot

The right way to open a proxy IP

Recommended hereDynamic Residential Proxy for ipipgo, their IP pool is as big as a food market. Focus on three metrics:
- Survival time: it is best to choose a short-acting agent of 3-10 minutes
- Geographic location: prioritize the use of the target site's local IP (for example, to capture the U.S. site, use the U.S. home broadband IP)
- Protocol support: must support socks5, more covert than http proxy

import requests
from itertools import cycle

 List of proxies provided by ipipgo
proxy_pool = cycle([
    'socks5://user:pass@us1.ipipgo:4000',
    'socks5://user:pass@us2.ipipgo:4000'
])

for page in range(1, 50): proxy = next(proxy_pool)
    proxy = next(proxy_pool)
    try.
        resp = requests.get(
            f'https://www.ebay.com/search?page={page}',
            proxies={'https': proxy},
            timeout=10
        )
        print(f'Page {page} captured successfully')
    except Exception as e.
        print(f'Failed with {proxy}: {str(e)}')

Six Tips to Prevent Sealing

1. Randomly cut the User-Agent for each request, don't always use the python default header.
2. Wait 2-5 seconds for the page to load and then operate it to learn how to browse in real life.
3. Higher success rate in the middle of the night than during the day 30% (personally tested and effective)
4. Don't fight hard when you encounter CAPTCHA, change the IP of ipipgo and retry.
5. Change agent authentication information weekly, don't let the platform figure out the pattern
6. Important data is divided into multiple accounts to catch, do not glean a number.

Practical QA Triple Strike

Q: Do free proxies work?
A: Never! 8 out of 10 free proxies have long been blackballed by eBay, and the remaining 2 are slower than a snail's pace. ipipgo's fresh residential IP success rate can go up to 95% or more.

Q: What can I do about the CAPTCHA that always pops up?
A: two methods: ① in the code to add a random scroll page operation ② change with ipipgo 4G mobile agent, this IP segment is sealed probability is much lower.

Q: How can I tell if an agent is exposed?
A: Add a detection mechanism in the script, if 3 consecutive agents have failed, immediately change ipipgo's spare IP pool, their API can change 500+ nodes in seconds.

Tabular version of the guide to avoiding pitfalls

One last rant, when using ipipgo remember to turn on theirAutomatic elimination functionThe first thing you need to do is to filter the nodes that are not working. Grabbing data on this matter with the guerrilla-like, talking about a fast in and out, don't let the platform to figure out your way. According to this program, you are guaranteed to double the collection efficiency, the sealing rate directly cut!
