Quick Help with Website Reverse Engineering

hey, it's a small task I'm a web dev trying to scrape a site, and I'm trying to list out all the slugs from the site. From the obvious methods, I've found like 10k pages, but I know there's 75k (another person has scraped the same site before) so I know it's doable just there's either an endpoint I don't know about or a sitemap I don't know about or something! and the site also has an app, so maybe different endpoints there if you're used to doing this kind of reverse engineering it could be a 10 minute find. couple hours at most. I don't need you to build a scraper, i already have that. I just need to find the method to find the slugs (urls) all the best!
