Love the business idea. In theory, all the book scraping is automated through Twitter api and then compiled through Amazon API. The page basically self-assembles using Nextjs template and API data call. You get paid via referral purchases. It's genius.
Curious: where do you get high-resolution book images. I wanted to add those to my own book list (https://kirillzubovsky.com/bookshelf) and haven't found a source with high res.
