Proxy IP Extraction: API interface for real-time proxy IP extraction

What exactly is the use of real-time proxy IP extraction?

Crawler friends should understand that the data capture is most afraid of IP blocking, a real example: last year, a small team of e-commerce price comparison, with a fixed IP to capture data in less than 3 hours was blocked, and then changed the real-time extraction of the proxy IP pool, the same day to complete the whole platform data collection.

this kind ofDynamic IP RotationThe technology is like putting a cloak on the crawler and changing to a new IP address for each request. This is especially true for scenarios that require a lot of high-frequency requests, such as:

1. product price monitoring (refresh every 5 minutes)
2. social media data collection (to prevent account linkage)
3. Search engine ranking tracking (to avoid frequency limitation)

Hands on with ipipgo's API!

Here take ipipgo's service as a demonstration, their interface design is very foolproof. First register an account to receive a free trial package (enough to test 500 requests), pay attention to these two key parameters:

Request example (Python version):

import requests

url = "https://api.ipipgo.com/v1/proxy"
params = {
    "api_key": "Your key",
    "count": 3,
    "type": "http"
}

response = requests.get(url, params=params)
print(response.json())

The return data looks like this, and it works straight away:

{
    "code": 200,
    "data": [
        {"ip": "112.95.235.66", "port":8080, "expire_time": "2024-05-20 14:30:00"},
        {"ip": "120.79.210.181", "port":8888, "expire_time": "2024-05-20 14:35:00"}
    ]
}

Guide to avoiding the pitfalls: 3 tips for choosing a service provider

Proxy IP services on the market are a mixed bag, so we recommend focusing on these three indicators:

1. Survival testing

Some IPs are dead when you first get them. ipipgo has a special feature - automatic filtering of invalid IPs when extracting them, and the measured survival rate can be more than 92%.

2. Speed of response

Don't believe the claimed millisecond response, measure it yourself! Use this command to measure the real latency:

curl -o /dev/null -s -w 'time: %{time_total}s' -x http://IP:端口 destination URL

3. Transparency in billing

Beware of hidden chargeback traps! ipipgo isBilling by number of successful requestsIf you are not able to access the IP address, you will not be counted as consuming the IP address.

Frequently Asked Questions First Aid Kit

Q: How many minutes does it take for the extracted IP to expire?
A：Check whether the protocol type matches, for example, visiting https website but using http proxy. It is recommended to enable automatic protocol adaptation in the ipipgo background

Q: Do all the returned IPs connect to timeout?
A: 80% is that the whitelist is not configured. Add the server public IP in the account settings, remember to bring /32 suffix (such as 1.2.3.4/32)

Q: How to optimize for high concurrency scenarios?
A: two tricks: ① set IP warm-up mechanism to get the spare pool in advance ② use the multi-location resolution function (ipipgo supports extraction by city)

Why do you recommend ipipgo?

After using it for over 6 months, these three features really smell good:

1. exclusive IP quality monitoring (automatic hourly update of the availability list)
2. Failure to retry compensation mechanism (automatic reissuing of new IPs for failed requests)
3. Dynamic pricing strategy (30% discount for late night hours)

Especially theirIP Survival Early Warning SystemThis detail design makes the stability of the program go up a notch directly by automatically sending replacement notifications 3 minutes before IP expiration. Register now also sends newcomers 48 hours of unlimited test package, enough to run a complete set of business processes.
