Space permissions using Confluence Server REST API

List of admins of a defined space in Confluence Server REST API

I need to get permissions from a defined space using Confluence Server REST API.
I am aware of the Confluence REST API Documentation at docs.atlassian where there is a REST resource for manipulating space properties - space/{spaceKey}/property, however it does not return any results.

I am also aware of Cloud REST API, but I’m looking for a Server one.

Thank you!
