How to do a price metasearch?

Question

Programming

Hello. Can you please tell me how to make a meta search for prices, without unnecessary information? That is just prices. I explain in more detail - For example, I have a search bar on the main page of the site, like Google, Yandex - in it the user must specify the exact or approximate name of the product, and my metasearch gives, for example, only the 3 lowest prices with a link to the online store, or one lowest. The bottom line is that the user goes to look for the lowest price for a product without too much information (without reviews, ratings and other unnecessary information). The most important thing is that the price really be the lowest in Runet at the time of the search. To everyone who took more than 1 second to read this question, or answered it, from a novice young girl webmaster, GIANT THANKS!!!!!!
