Mobile Applications Market Brands

Question

Good afternoon, I'm developing a mobile app but I'm stuck with something. What I want is to be able to compare the prices of supermarkets' products in my application, but the problem is how is it possible to access the products of the brands? And how can I add them to my app? Do they publish the Firebase of the grocery stores in a public place? I could not find it on google. Is it subject to credit to use these products in my own application because there will be no sales in my application, only comparison

Thanks in advance.
