HermanFassett/youtube-scrape ? reverse-engineered prompt

Build me a simple web app that acts like a YouTube search API.

I want to type in a search term and get back clean JSON with the search results, including videos, channels, and playlists when they show up. It should support a query parameter for the search text, and if there are more results, let me pass the next page token and search key to continue paging.

Please make it easy to run locally and in Docker, and if there’s a tiny demo page or landing page for the API, that would be great too. The main goal is that someone can hit an endpoint like /api/search and get useful YouTube results without needing an official API key.

If you need to check current docs or adjust anything for YouTube changes, go ahead and look it up online. Keep the response format consistent and readable, and make sure errors are handled gracefully.
