1. "This method" refers to all steps or explanations I write on this article, Jefrydco: What If We Could Search Any Keyword from Any YouTube Video through Its Closed Captions Text?.
2. "The API" refers to all the API available in https://cari-teks-video-api.vercel.app/api.
3. All of this method is pure entirely for research and experimental purpose.
4. If YouTube decides to change the behaviour or use some other way, this method probably couldn't work anymore.
5. Since the API is deployed on free version of Vercel, they do have a restriction for function invocation. If suddenly the API inaccessible, it seems it is already hit the limit.
6. Because of point number 4 and 5, I can't guarantee that the API will work forever. But I do regularly check whether it's still fine or not.
7. Please don't use it on production. I won't responsible for any side effect usage of the API on production.
8. YouTube already have YouTube Data API for Captions to provide the official way of accessing closed captions. Please use that instead of this if you want to use a similar feature on production.
9. If you found any bug, please submit an issue on the GitHub repository, Cari Teks Video API.
