Wholesale access to the products of these types of websites

[sanjay123]

Hello friends; I am thinking of setting up a site like ozhat.com.tr but adding each product individually would take up too much of my time. The product codes of the products offered on this site must be universal because many sites provide services with the same product code. I asked a few people and it seems they share these products in the form of a database. How can I find the site or company that distributes the database of products, or if it's easier, pulling the database directly would be better. I would appreciate it if those who have information could help. If I posted this topic in the wrong place, where should I post it? Have a nice day..
