How can you grab price lists from supplier sites in Joomla 3?

Question

CMS

The crux of the matter is as follows. Due to the unstable situation of the national currency, there was a need to very often automatically update price lists from suppliers' websites in order to maintain up-to-date information on the cost of products. The site is built on Joomla 3. The task is to take data from the price lists that are placed directly on the sites and publish (update) in the catalog of my site. I will be able to implement the entire exchange, but for this I ask for advice on how exactly this is implemented (modules, components, third-party software). Thanks in advance!
