Stephane, I haven't looked at the cloudfork code in detail but I'm sure you can reuse the generic part of setting up the communication. All Amazon Web Services communicate in the same way - its basically about signing your requests with an HMAC signature using your secret access-token. Each API then defines certain query parameters. To do your ISBN queries you can have a look here: http://docs.amazonwebservices.com/AWSECommerceService/latest/DG/index.html?ItemLookup.html You will just need to supply the parameters IdType=ISBN and ItemId for the actual ISBN. Depending of the amount or kind of information you want to get you can specifiy certain "ResponseGroups" in the request e.g. "Large" or "Medium". Hope that helps.
