I went through the article and it links to a repo at the end but I received a 404

Is it possible to read the whole post, without sharing my email?

This is extraordinary reverse engineering. I particularly liked the part about using their own signer but outside of the apk. LLMs have effectively taken the Ads most for so many of these companies. I can just have an AI rebuild their website to a UI I like using this reverse engineered mobile API.

What data does this method retrieve?

yt-dlp already gets a lot of metadata like: duration, title, description, timestamp, view_count, like_count, repost_count, comment_count, save_count, etc.
