how to add label to the confluence pages under certain hierarchy in space

[Kyoungsun Cho]

I'd like to add label into pages under certain hierarchy in space.

Is there any API to support this function?

If possible, it would be better if there is a way to automatically generate labels by extracting or parsing the page title or contents.

To add labels to pages under a hierarchy in a Confluence space-
Navigate to the parent page and expand the page tree.
Open each page, click on Add Labels, and add the desired labels.
For bulk labeling, use Confluence Apps like Label Manager or scripts via the Confluence API.
