Free AI Web Crawler Tools: Top 5 Free AI Agent Crawler Tools

First, why do you have to use a proxy IP for data collection?

Do network crawler friends understand, the most headache is to be the target site blocked IP. to give a real example, last year, an e-commerce friends want to catch the price of competing products, the results of their own home broadband continuous access, less than half an hour IP will be blacklisted. At this time, the proxy IP is like a martial arts novel "disguise", so that each request is like a different person in the visit.

There are a lot of free tools on the market, but they hide a lot of potholes:Either the IP pool is pathetically small or slow as a snailThe more pitiful is that some of them are actually recording users' data secretly under the banner of free. What's even more pitiful is that some of them are actually recording user data secretly under the banner of free. So if we want to save money and be reliable, we have to find the right way.

Second, hand to teach you to choose the proxy IP tool

Here's a tip for the guys, there are three hard indicators to look for when choosing a tool:

1. the amount of concurrent request support (at least 10 threads should be able to open at the same time)
2. IP survival time (it is recommended to choose a dynamic IP, survival of 3-5 minutes just)
3. protocol compatibility (must support HTTPS and Socks5)

To give a real-world scenario: when writing a crawler in Python, it is recommended to configure the proxy like this:

import requests
proxies = {
    'http': 'http://username:password@gateway.ipipgo.com:9020',
    'https': 'http://username:password@gateway.ipipgo.com:9020'
}
response = requests.get('destination URL', proxies=proxies)

Third, the family products to show a picture

Speaking of which, I have to introduce you to ouripipgo, this is not the old king selling. Their dynamic residential IPs are particularly well suited to crawler scenarios, to tell you a few honest truths:

Especially theirs.API Extraction FunctionThe first step is to make it easier for the user to get to the IP pool, and to make it more convenient for the user. After registration directly in the background to generate the extraction link, the code to put a timed task to automatically update the IP pool, completely without manual staring.

Fourth, to avoid the pit guide to see here

Three common mistakes newbies make:

1. cheap to use free IP (99% are invalid)
2. forget to set the timeout parameter (resulting in the program stuck)
3. single IP high-frequency access (change of armor must also pay attention to the frequency)
