I like the idea of being able to search and browse Youtube infinitely, but having to enter API key is a bit rough, yt-dlp support searching out-of-the-box and doens't require API at all.

Describe the solution you'd like
Use yt-dlp instead, with --flat-playlist it's very very fast:

yt-dlp ytsearch10:SEARCH --get-id --get-title --flat-playlist

10 = number of result, of course it must be used with --flat-playlist to increase searching speed by ten forth.

Describe alternatives you've considered
yt-dlp instead of curl+API

Additional context
Should be good enough information.

Is there a way of getting channel information for each video as well?

Yes, a small issue is short videos doesn't return channel name, but shorts are irrelevant so we can just group NA as Shorts:

yt-dlp ytsearch10:fireemblem --flat-playlist --print id,title,channel
