List of items with rank and UPC

Currently I’m using with inventory labs/Scoutify and whenever you scan a barcode or use a UPC they of course give you the rank of how the item is selling (like 25,000 out of 3,000,000) which is of course useful if you have a specific item in mind however I find it less useful as far as finding new items online for example, so my question is has anyone found any software or site that has like the top 10000 of a given category with UPC codes so you can look for items on sites like eBay for them? Thanks in advance.
