Amazon MWS Documentation


Returns the current competitive price of a product, based on ASIN.


The GetCompetitivePricingForASIN operation is the same as the GetCompetitivePricingForSKU operation, except that it uses a MarketplaceId and an ASIN to uniquely identify a product, and it does not return the SKUIdentifier element. If you do not have the ASIN for a product, you will first have to submit the ListMatchingProducts operation for disambiguation.


This operation is available in all marketplaces.


Maximum request quota Restore rate Hourly request quota

Operations in the Products API section that send lists of items as input parameters have restore rates that are measured by item. For information on per-item throttling, see Throttling in the Products API. For definitions of throttling terminology and for a complete explanation of throttling, see Throttling: Limits to how often you can submit requests in the Amazon MWS Developer Guide.
