+## Description
+We offer you a ready-made extractor of products from Allegro. It receives the search output of Allegro.pl, as well as detailed information about the goods.
+
+The scraper is very easy to integrate with your site. The site will make a regular HTTP-request to the crawler and receive in response data in JSON format. Extractor is universal, it doesn't matter what CMS or engine your site is based on.
+
+Other people's Allegro scrapers have stopped working, but this parser continues to work stably and quickly.
+
+The data scraper can work "on the fly", that is, it can extract data from Allegro in real time when a request is made (from the point of view of your site, when a user visits some page). This ensures 100% data relevance and reduces the load on the server.
+Also, this Allegro crawler can be used to constantly scraping all the products, that is, saving and updating a full catalog of products.
