Using SimilarityLookup

When you put an item ID in a SimilarityLookup operation requires, the response includes similar items. In previous sections, you saw that you can use the Similarities response group to return similar items. So, why use SimilarityLookup? This operation gives you the following advantages:

  • SimilarityLookup provides a number of request parameters, such as MerchantId and Condition, to help filter the response

  • SimilarityLookup is able to use many response groups to customize the information in the response

  • You can specify more than one item in a request and find items that are similar to all of them, or similar to each item in the request

The following request returns items similar to the specified ASIN. 

http://ecs.amazonaws.com/onca/xml?
Service=AWSECommerceService&
AWSAccessKeyId=[AWS Access Key ID]&
Operation=SimilarityLookup&
ItemId=[ASIN]

The following XML is a snippet of the full response.
