Api and Scrap in real time from Allegro PL

Hey Developers, nice to meet you. I need a script to synchronize the products on [login to view URL] in the car parts category in real time with the site they are building. Problems you may encounter: 1 - allegro blocks requests (so you need a proxy) 2 - we are talking about over 10,000,000 products. 3 - APIrest by Allegro does not work to extract from their server directly ... My question is: 1 - Which solution do you choose for the script and why do you think it is the perfect one? 2 - Do you think you can extract a million products in less than an hour? 3 - will the solution you choose be able to find the products with the help of google directly on my site? 4 - which is the perfect solution to be able to update the page in real time (ie if the product is sold, to have zero stock with me) A site that would be a good example is: [login to view URL] With the help of the product id on [login to view URL], find any article in the shortest possible time. This site has any product, even those posted on allegro 10 seconds ago .... has the ability to find on google ... and also has the search bar with which to find a product on allegro in a request way as their owner, that is, without any expectation Looking forward to any type of offer, thank you and wish you a wonderful day! Sincerely, Sergiu
