Need Discord Monitor to track Items of Product Websites

I want a Discord Monitor that checks if items are in stock at certain websites. The items that I track, sell out in seconds. So we need to be able to track with API instead of just refreshing the page. I am not sure if we still need Proxies with API? The websites I want tracked are: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] so basically I can tell the to monitor this item from [login to view URL] and as soon as it is in stock it will post a message with a link saying it is in stock. We can do this by just giving the links to the monitor or something else? I will be using [login to view URL] to host the monitor Also I want to able to add items I want from those website with a command. So basically +add and I can add a link or ASIN for Amazon and it will add it. I also want to be able to add a channel to each added item. So basically when I add +add and add a link or whatever then it will ask me what channel do you want to be notified of the restock. You can see an example in the pictures.
