How to set read only Restful

I see overall steps

You can access the file system namespace through an access point. Root users can create an access point on the namespace, and initially only the root user has privileges for that access point. The root user can create an access control list (ACL) to provide read privileges for additional users

from https://www.dell.com/support/manuals/en-in/isilon-onefs/ifs_pub_onefs_api_reference/access-points?guid=guid-f290de97-f89c-4c05-a457-e30ed888e89c&lang=en-us

but two questions.

1. example given is GET commands, anyone know equivalent cli process ?

2. Does this access supersede namespace directory and file permissions, i.e. if I use

a user rest_access to get ACL's on a file /ifs/a/restricted/file

can the ACL be read by the user rest_access if its not given read and traverse access to get ACLS ?
