More cold api proxy: niche API proxy access program

The Proxy Doorway Hidden in the Code

When many programmers engage in data collection, they come up to grab the public APIs of well-known platforms, but some e-commerce platforms of BijouMerchandise Inventory InterfaceLogistics CompanyWaybill Track Interface, these APIs hidden in the nooks and crannies are the real - data goldmine. These types of interfaces tend to have simple validation mechanisms, but there's a fatal problem - theIP access frequency limitation, this is where proxy IPs come in to break the ice.

Survival rules for cold interfaces

I recently helped a friend with a provincial government platform.Enterprise credit inquiry interfaceThey used a trick: spreading the query requests to server IPs in different localities, which could only work if they could get localCarrier Native IPFor example, if you want to check the data of Hangzhou enterprises, you have to use the dynamic residential IP of Hangzhou Telecom.

import requests

proxies = {
    'http': 'http://user:pass@hz-dynamic.ipipgo.net:24000',
    'https': 'http://user:pass@hz-dynamic.ipipgo.net:24000'
}

response = requests.get('http://xxx.gov.cn/api/enterprise?code=91330101', proxies=proxies)

Look at the proxy address in thehz-dynamicThis prefix, which is ipipgo'sDynamic city node labeling. Their family has deployed in Jiangsu Suqian, Guangdong Dongguan, these second and third tier cities, especially suitable for those who need toSimulate local accessThe Scene.

The cat's meow in enterprise solutions

Last week there was a client who does hotel price comparison and they accessed a travel platform'sHousing state real time interface. Starting a frantic request with a pool of public proxies resulted in triggering the platform'sTraffic cleansing mechanisms. Then switched to ipipgo'sStatic Home PackageThe survival rate is directly pulled up to full capacity by binding fixed IPs to each business thread, along with random UA and mouse track simulation.

Real life example: bypassing the siege of a map API

A logistics company wants to acquire in bulkRoute planning data, but the map service provider's interface hasLongitude and latitude deviation detection. We used ipipgo'sMobile Base Station IPthat successfully fools geofencing by simulating the location drift of a real user. Here's a pitfall: remember to add the request header with theX-Forwarded-Forfield, do a double validation of the export IP and the proxy IP.

headers = {
    'X-Forwarded-For': '120.26.103.215', 'User-Agent': 'Mozilla/5.0 (iPhone; CPU iPhone OS 13_2_3 like Mac OS X)'
    'User-Agent': 'Mozilla/5.0 (iPhone; CPU iPhone OS 13_2_3 like Mac OS X)'
}

QA session

Q: What should I do if my proxy IP often times out?
A: 80% of them are using a shared proxy pool to change ipipgo'sExclusive Static PackageEach IP has its own bandwidth.

Q: What if I need to use both domestic and foreign agents?
A: Their houseTK LineSupport for mixed nodes, remember to add the location_code field in the API request parameters to specify the region

Q: Is the authentication method too complicated?
A: Generated on the consoleWhitelist IP+KeyDouble authentication, more secure than traditional account passwords, and no need to write dead credentials in the code

One final rant: many cold APIs now have perverted protection compared to mainstream platforms, so it's recommended to start with ipipgo'stest environmentRunning through the process, their error logs will clearly tell you whether the IP is blocked or other rules are triggered, which is much better than some platforms that only return 500 errors.
