@Edent nice find with the embedded JSON for the Kobo Wishlist! i've been trying to scrape the wishlist in order to fetch the books into my "To Read" list on my static site.
were you able to get around the captcha Kobo uses? when using a headless browser (like Puppeteer), i just got the "are you a human?" prompt when drying to sign in to my Kobo account.
