Accessing power-up rems by ID using the API

How do I account for power-up Rems in the backend API?

Currently, attempting to query the IDs of powerup Rems returns {"found": "false"}. If I want to find out if a Rem is tagged with e.g. “Status: Draft” or “Extra Card Detail”, is there a way to do so via the backend API without having to hard-code their IDs?
