Walmart Product Identifier Application

We need an application that identifies a common factor to link products between Walmart USA and Walmart Canada (similar to how ASIN is used on Amazon) . This common factor will be the identifier that we provide as input to retrieve the following data:

Common Factor - The unique identifier (similar to ASIN on Amazon) used to link the products between Walmart USA and Walmart Canada. This will be provided as input to get the relevant output.

Price in USA - The price of the product on Walmart USA( buybox price ) and for more sellers 2 more sellers price

Total Seller Count - The total seller count, which should be displayed separately for both Walmart USA and Walmart Canada.

Buy Box Price in Canada - The price at which the product is available in the Buy Box in Walmart Canada. If the product is not available, the output should state "No one selling."
Sellers: The names of at least four sellers offering the product. If there are multiple sellers, the application should list the seller names along with their respective prices.

Own Seller Column: A separate column showing if we are seller what is our price

We will input UPC/EAN for walmart USA and it will search data in both Walmart USA as well Walmart Canada and vice-versa and give us the expected output
