Price Crawl: Residential agents get real-time prices from e-commerce companies.

Residential agents are great for e-commerce price monitoring.

Doing e-commerce friends have been worried recently, the platform every now and then to change the price, competitors and follow closely. It is simply unrealistic to keep an eye on them manually, and if you use a crawler, the IP will be blocked in a few minutes.Residential AgentsThis is a godsend, especially with a service like ipipgo that provides real home network IPs that are much more hidden than regular server room proxies.

For example, if you are a digital accessory owner and use an ordinary proxy to catch the price of a certain east, you will be banned for 20 IPs in half an hour. ipipgo's residential proxies were replaced, and they were not found for three days. The reason for this is that it is not a good idea to use the same proxy for the same purpose. Because the platform sees the normal visit of real users across the country, just like ordinary customers in the price check.

Hands-on price monitoring system

There are just three preparation tools:
1. An environment capable of running Python
2. requests library (installation command: pip install requests)
3. ipipgo's residential proxy package (dynamic residential recommended, IPs change automatically)

import requests
from time import sleep

def get_price(url):
    proxies = {
        "http": "http://用户名:密码@gateway.ipipgo.com:端口",
        "https": "http://用户名:密码@gateway.ipipgo.com:端口"
    }
    try.
        response = requests.get(url, proxies=proxies, timeout=10)
         Add your parsing code here
        return price
    except Exception as e.
        print("Crawl error:", e)

while True: current_price = get_price("")
    current_price = get_price("https://某电商商品链接")
    if current_price < preset_price: send_alert("current_price = get_price(""))
        send_alert("Price dropped!")
    sleep(300) 5 minutes

Watch out for the three pits:
1. Don't request too often, 3-5 minute intervals are recommended.
2. Remember to randomly change User-Agents
3. Important data is validated twice to avoid agent nodes from jerking around.

Why do I have to use a residential agent?

There is another hidden benefit of using ipipgo, their IP pool is updated daily with more than 30%, which is especially suitable for scenarios that have to be monitored for a long time. I've tried a certain cheap one before, and as a result, I didn't change my IP for half a month, and I was finally caught by the platform.

A practical guide to avoiding the pit

The most frequently encountered problem isCAPTCHA pop-up. Don't rush to change your IP at this point, try these two tricks:
1. Add random mouse trajectory simulation to the code.
2. Adjustment of equipment information in the request header
If that doesn't work, then cut to ipipgo's alternate IP channel, their API can change IPs in seconds, much faster than doing it manually.

Frequently Asked Questions

Q: Will residential agents be slow?
A: Now home broadband are 100 megabytes to start, ipipgo nodes measured latency in 200ms or less, completely enough!

Q: How do you ensure the accuracy of the price data?
A: It is recommended to crawl with 3 different regions at the same time, taking the middle value. ipipgo supports opening multiple proxy channels at the same time!

Q: What should I do if I encounter IP blocking?
A: Immediately contact ipipgo customer service to change the IP segment, they have a special anti-blocking IP pool, pro-test effective!

Lastly, don't try to buy the cheap shared proxies that cost a few dollars. If you want to do price monitoring, you need to use an exclusive residential IP, which is more expensive, but less worrying. Especially like ipipgo can provide API dynamic switching, long-term use but more cost-effective. There is a big promotion rely on price monitoring to get a head start, a day to earn back three years of agency fees, this investment is absolutely worth it.
