Amazon provides product advertising api for users to advertise amazon products. It provides details like items for sale, customer reviews, seller reviews, as well as most of the functionality that we see on www.amazon.com, such as finding items, finding similar items, displaying customer reviews, and product promotions.
The api is free.
The function (itemsearch) takes a range of parameters to specify the customers requirements to view a set of items. The api provides access to the Amazon database which is called catalog. The results can be narrowed down by specifying search indices(eg:- to narrow the search results to just books category).
The search results are returned in XML format.
Using the service requires the user to register for an AWS access ID.The web service supports both REST & SOAP request. It supports languages like: JAVA, C#, PERL, PHP.
The Amazon api provides customer reviews as part of their api which could be integrated into Shopster so that the users can view reviews for their selected products. Reviews hosted by a trusted host like Amazon will add value to the application.
