How to get the users having access to an unrestricted page?

[Himanshi Badgali]

I am looking for a suitable confluence REST API to get all the users having access to an unrestricted page.

If you look at the content properties you can get the list of groups/users that can view the page.  API doc below:

If you need to expand the groups into users:

If there were restrictions, I know you said w/o restrictions, this would be what you'd want to look at, REST API wrt getting restrictions is here:
