How do I get info about a Youtube video's chapters from the API?

Question

Recently, Youtube added the ability to break up their videos in the progress bar into sections called "chapters".

https://support.google.com/youtube/answer/9884579?hl=en

Currently I am able to get info about a video from the Youtube API. However, it doesn't seem like there's any info about a video's chapters, and I haven't found anything in the API documentation about chapters. Am I missing something, or is there simply no way to get chapter data yet?

Answer 1

As far as I know, such data is in plain text in the description of the video.

So, you can use the following example:

Video used in this demonstration: Top 10 Monsters with 2500 Attack in YuGiOh
