How to bypass PerimeterX

You’ve found the website you need to scrape, set up your scraper and fired it, just to sadly realize PerimeterX has blocked you.

PerimeterX’s dynamically complex bot detection system relies on server-side and client-side checks to distinguish humans from bots. It deploys several layers of protection and, for the most part, manages to do its job without interrupting the user experience.

But don’t fall into despair! There are a couple of things you can try to bypass PerimeterX (called HUMAN now) before giving up on your goal of scraping that delicious data.

Python, Selenium for custom browser automation scraper

Recently we’ve got the tricky website, its data being of dynamic nature. Yet we’ve applied the modern day scraping tools to fetch data. We’ve develop an effective Python scraper using Selenium library for browser automation.

AirTable scrape challenge

I need to get info from AirTable, see a table example.

The problem is that data are loaded highly dynamically. HTML contains only the information that you currently see on the browser screen.

enter image description here

If there are a lot of records then it is difficult to collect such a table. One of the possible ways is to calculate the size of the screen and rows in the table. Then using the browser automation and use to make a script that will scroll through it bit by bit and collect data.

Is there any other feasible way to get data of a table? For example there is a HTTP requests coding way to get dynamic data.

JS infinite scroll does not work for AirTable either.

Please comment down here if having some tips, hints.
