RTMS credit consumption per minute, and whether the initiating participant needs a paid plan

Two questions on RTMS. My current understanding is that the app developer’s account
holds the credits, that Basic hosts are supported when the developer account has
Developer Pack entitlement, and that RTMS requires a participant-initiated REST start
targeting an invited participant who has joined. Please correct any of that if it’s
wrong.

  1. Credits per minute. How many credits does one minute of RTMS consume, and is the
    rate different for raw audio versus the diarized transcript stream? I can see the
    Developer Pack credit packs, but I can’t find the per-minute consumption published
    anywhere. I’m trying to decide whether to include this in a subscription tier or meter
    it separately, and the two options are very different products.

  2. Initiating participant’s plan tier. Basic hosts are confirmed supported when the
    developer account has Developer Pack entitlement. Does the same hold for the initiating
    participant — the account whose OAuth token makes the PATCH
    /live_meetings/{meetingId}/rtms_app/status call with
    meeting:update:participant_rtms_app_status? Since that’s the authenticated caller
    rather than the host, I want to confirm a Basic-plan participant can initiate before
    assuming it.
