Market Data Providers: Market Data Proxy Collection

Why does market data capture always flop?

Anyone who's been doing data collection for a long time should have encountered this crap before: just grabbing two pages and thenIP blockedI'm not sure what I'm talking about. I'm talking about the data.be missing an arm or a legThe target site loads slowly like a snail. The culprit of these problems, ninety-nine percent of nine are the site of the anti-climbing mechanism in the demon.

For example, an e-commerce platform price monitoring, if the local IP to sweep every day, not three days into the blacklist. At this time, we need a proxy IP as a stand-in, each visit to change a "vest", so that the site thinks it is a normal user browsing.

How did proxy IPs become body armor for the data battlefield?

There are two main types of common proxy IPs on the market:

Take ipipgo'sDynamic residential agent poolFor example, their IP resources cover 200+ countries and regions, and each request automatically switches the export IP. When testing the capture of a recruitment website, the continuous collection of 8 hours did not trigger any blocking, and the success rate remains above 98%.

Hands-on deployment of proxy IP harvesting

Here's a Python demonstration of how to access the proxy service via the ipipgo API:

import requests

 Proxy configuration from ipipgo
proxy_api = "https://api.ipipgo.com/get?key=你的密钥&type=json"

def get_proxy():
    resp = requests.get(proxy_api).json()
    return f "http://{resp['ip']}:{resp['port']}"

 Example request with proxy
url = "https://目标网站.com/data"
proxy = get_proxy()

response = requests.get(
    url,
    proxies={"http": proxy, "https": proxy},
    timeout=10
)
print(response.text)

Note that you have to change the code in thekeysReplace it with your own credentials applied for in the ipipgo backend. It is recommended that the proxy acquisition interface be made into a standalone function for easy subsequent maintenance.

Collection of practical guide to avoid pitfalls

1. IP switching frequencyDon't be too straight: some newbies like to change IP for every request, but it is easy to trigger anomaly detection. It is recommended to set 5-20 requests to change IP once according to the anti-climbing strength of the target website.

2. request header masquerading asTo be in place: remember to bring your normal User-Agent, and it's a good idea to have 10-20 UA's from common browsers to rotate through.

3. timeout settingDon't be lazy: it is recommended to set connect and read time separately, for example, 3 seconds for connect and 15 seconds for read to avoid dead waiting.

Frequently Asked Questions First Aid Kit

Q: Obviously used proxy IP or still blocked?
A: Check if the cookie carries user characteristics or the request frequency is too high. You can try ipipgo'sAutomatic cookie clearing mode, resetting the session with each request.

Q: What should I do if I need to collect overseas websites?
A: ipipgo's overseas nodes support selecting IPs by country/city, for example, to capture Japan's Rakuten market, you can directly specify the Tokyo server room IP.

Q：Collecting half of the IP suddenly does not work?
A: This situation may be the target site updated anti-climbing strategy, it is recommended to contact the technical support of ipipgo, their IP poolsAutomatic update every 5 minutesOnce, the response was pretty quick.

What are the hard indicators to look for when choosing a proxy service provider?

Here's a self-test checklist:

• Is the IP pool large enough (ipipgo currently has 30 million + dynamic IPs)
• Availability of failure retry mechanism
• Whether or not HTTPS/SOCKS5 protocol is supported
• API responsiveness (measured ipipgo's interface returns within 200ms on average)

Finally, data collection is a long-lasting war. Instead of spending time tossing free proxies, it would be better to go directly to ipipgo, a professional service that saves time and digs up more business value is more cost-effective. After all, free is the most expensive, this is absolutely true in the field of proxy IP.
