Amazon UPC ASIN Look Up

I need to be able to input bulk UPC codes on amazon into a script tool. I will need a CSV output file. I need to know ASIN numbers, and where there are multiple ASIN numbers then separate them one per line I also need Titles for each ASIN, sales rank(BSR), buy box sell price, Buy box seller name, and Yes/No result if Fulfilled by Amazon Not all UPCs will be 12 digit, so script /tool created must be able to deal with adding leading zeros if needed.
