クラウド上からyoutube-transcript-apiを実行したい

実現したいこと

クラウド上（Renderを使用予定）から、指定したYoutube動画の字幕を取得したいです。
Ruby On RailsからPythonで作成したスクリプトを呼びだすことで実現しようとしています。

現在はCodespaces上でRailsの環境を作成し、そこで作成をしています。

発生している問題・分からないこと

字幕取得部分でエラーが発生します。
エラー文を読む限り、Youtubeはクラウドからのリクエストをブロックしているため、処理ができないのではないかと思っています。

30YouTube is blocking requests from your IP. This usually is due to one of the following reasons:
31- You have done too many requests and your IP has been blocked by YouTube
32- You are doing requests from an IP belonging to a cloud provider (like AWS, Google Cloud Platform, Azure, etc.). Unfortunately, most IPs from cloud providers are blocked by YouTube.
33
34There are two things you can do to work around this:
351. Use proxies to hide your IP address, as explained in the "Working around IP bans" section of the README (https://github.com/jdepoix/youtube-transcript-api?tab=readme-ov-file#working-around-ip-bans-requestblocked-or-ipblocked-exception).
362. (NOT RECOMMENDED) If you authenticate your requests using cookies, you will be able to continue doing requests for a while. However, YouTube will eventually permanently ban the account that you have used to authenticate with! So only do this if you don't mind your account being banned!
37
38If you are sure that the described cause is not responsible for this error and that a transcript should be retrievable, please create an issue at https://github.com/jdepoix/youtube-transcript-api/issues. Please add which version of youtube_transcript_api you are using and provide the information needed to replicate the error. Also make sure that there are no open issues which already describe your problem!
