Add product to cart by url in magento 2

On the configuration page, I define the product id, now I need to call the url: http://localhost: 3000/custompoint/secret/addprizeproduct in the browser and add this product to the cart – this is necessary so that if a prize product is defined on the site, the user can click on the link and add item to cart. How i can you make this in Magento 2?
