Client's Objective
I am looking for a data scrapping expert. This is not for beginners. My data source has over a million records with IP detectors that detects the scrappers if a particular IP visits pages more than 10 times, also it has cloudflare protection and Bot detector being invoked after a few visits. The website even limits the number of times humans can visit the data before they're given a cooldown period.
It has 3 levels of securities and almost every scrapper out here and on Fiverr declined the job saying it's not doable. I do not intend on wasting any more money.
Project Specification
Search for businesses going by the alphabetical order in the business listing page
For each alphabet, Around 30,000 business records are available
Retreive all the data for each business, mainly:
Save all the html data in a tabular form in an XLS or a CSV file
Project Timeline
Client's TImeline: Flexible but less than 3 Months if possible
Scripting: 3 Days
Execution: 7 Days
Delivery: 10 Days
Challenges/Proposed Workarounds
Challenge: Upon initially auditing of the website, it was found that a lot of businesses were repeated through out multiple pages which made the script inefficient and slow constantly hitting on links that were already previously targeted.
Workaround: Inspecting the network requests revealed that all the business data were being fetched from an external database as an API call, Instead of the alphabetical approch, it made much more sense to directly call the API with the business id no which was a serialised ID. This helped the scraping speed up by 30x!
Challenge: The website was one of the toughest to beat in terms of security as it possibly hindered every approch, Apart from just IP blocking it also blocked the network and device so no devices connected to the same network was ever able to make a request.
Workaround: A carefully scripted program that used multiple levels of anti detection measures was developed.
