I wrote that tool by myself, but 1/3 of found ASINs are incorrect. The problem is I can identify incorrectness only manually. I ask you to write such a program from scratch.
• search in the USA for Prime products only
• match amazon product by eBay title, images, and item specifications like color, weight, and quantity
• bypass captcha
• preferably, be written in JS, so I can use it in my software
How do you plan to identify and filter incorrect products?
