Search Engine Results API: SERP Data Interface

When crawlers meet CAPTCHA? Try the Proxy IP Clay

Friends who do data collection know that search engine results page (SERP) data is like a gold mine. But directly call the API interface, nine times out of ten will be the target site choke. This is the time to use someProxy IP dexterity, ipipgo their home tested to bypass most CAPTCHA blocking.

Teach you how to interface with SERPs using proxy IPs.

In the case of Python, for example, there are three key points to remember when docking with the requests library:
1. Each request mustRandom IP change
2. Request intervalsLike a real person.(aliquot seconds)
3. Immediately upon encountering a CAPTCHAcut alternate channel

import requests
from ipipgo import get_proxy Here's the kicker! Calling ipipgo's SDK

def serp_crawler(keyword):
    proxies = {
        
        'https': get_proxy(protocol='https')
    }
    headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64...'}

    try: resp = requests.get('https')
        resp = requests.get(
            f'https://api.example.com/search?q={keyword}',
            proxies=proxies,
            headers=headers, timeout=10
            timeout=10
        )
        return resp.json()
    except Exception as e.
        print(f'Crawl error, switching IPs automatically: {str(e)}')
        get_proxy(release=True) force release of the problem IP

Top 3 guide to avoiding the pitfalls of choosing a proxy IP

With the varying agency services on the market, these three parameters must be kept an eye on:

Old driver common overturn scene QA

Q: Why do I still get blocked after using a proxy?
A: Ninety percent of it is due to IP reuse, ipipgo'sDynamic Tunneling ModeCan automatically change the IP, more than a single extraction of the build

Q: Do I need to maintain my own IP pool?
A: Never! We've tested self-built IP pools and the maintenance cost is three times more expensive than buying the service. It's more cost-effective to just use someone else's ready-made service!

Q: How to judge the proxy IP quality?
A: Focus onSuccess rate of requestsrespond in singingRetesting mechanismThe first thing you need to do is to get a good deal on the price of the product. Like ipipgo's backend can see the real time success rate, and anything below 95% can just be passed over

Tell the truth.

Engaging in data collection is like fighting a guerrilla war, don't expect to eat everything in one move. Use services like ipipgo to pay attention to the combination of strategies:
1. Open during high-frequency visitsshort-lived IP pool
2. For long-term mandatesStatic Residential IP
3. Immediately upon encountering a CAPTCHACut alternate API channel
Remember, there are no methods that always work well, only improvised sets. Keep a few extra sets on hand so that you don't fall off the wagon when it comes to counter-crawling upgrades.
