REST service in Dedicated Tenancy SaaS

I’ve seen mention that MT SaaS has the REST services on - does DT as well? If so, can someone point me to a document that covers accessing them? I’ve tried re-formatting some of the on-prem samples I’ve seen to guess at the path for DT but i’m striking out.

REST is not enabled by default in Dedicated Tenancy. It can be enabled via a request made through Support, and we’ll provide the particulars on how to access.

Is it enabled by default on MT Saas?

Rest had been enabled by default since 10.2 since we require it to run the active home page amongst other toys
