I have the detail information of books including ISBN, title, and author, is there anyway to get ASIN and the price so that i could make links to the product page on amazon directly?Thanks.

If you have 10 digit ISBN numbers, the ASIN number is actually the same.

What are UPCs, EANs, ISBNs. and ASINs?

Amazon Standard Identification Numbers (ASINs) are unique blocks of 10
letters and/or numbers that identify items. You can find the ASIN on
the item’s product information page at Amazon.com. For books, the ASIN
is the same as the ISBN number, but for all other products a new ASIN
is created when the item is uploaded to our catalogue.

how do i get an ASIN number?

Each product sold on Amazon.com is given a unique ASIN. For books
with 10-digit ISBN, the ASIN and the ISBN are the same. Books
without an ISBN and other products are also assigned ASINs.

With the ASIN known, you can then use the ItemLookup Amazon API command to retrieve the price.
