@jdepoix Thanks for feedback. I guess I misunderstood, I thought we should not refactor anything and use existing modules to create YoutubeTranscriptAsyncApi class. That's why there is too much code...

Hi @jdepoix, I'd like to work on this issue to add async support for better performance. I've implemented the core logic using `httpx`, including classes like `YoutubeTranscriptAsyncApi`, `TranscriptListFetcherAsync`, etc. Tests...

@CodeWithOz Of course! Here I created a [draft pr](https://github.com/jdepoix/youtube-transcript-api/pull/514) for review.
