How to check whether cart is mine or other shop using Amazon SP-API productsPricing

I would like to know which attibute specifies the cart is mine or other shop.

This is becasue there are too many attibutes that we could get and it dose not state clearly which one is which.

I am refering following.

Best regards,

I went through all the attributes, but, I cannot find myself.

Solution

It doesn't look like Amazon indicates whether your item is the item with the best price. You can use the getCompetitivePricing() call to get a list of prices that compete for a given list of ASINs. See documentation here: https://developer-docs.amazon.com/sp-api/docs/product-pricing-api-v0-use-case-guide There is also a newer api that has a getFeaturedOfferExpectedPriceBatch() call to get the price that a seller can use to become the featured offer, perhaps that is what you are looking for. https://developer-docs.amazon.com/sp-api/docs/product-pricing-api-v2022-05-01-reference
