Confusion between /v2/conversations and /v2/analytics/conversations endpoints

I’m trying to grab call data for our WFM adherence reports but I can’t tell when to use the real-time endpoint vs the analytics one. I called /api/v2/conversations/details and got the live state, but I need historical data for the last week. Should I be hitting /api/v2/analytics/conversations/details/query instead? Here is the snippet I’m using:

response = client.conversations_api.get_conversations_details()

The analytics endpoint feels like it has a delay. Which one actually gives me the final disposition I need for the schedule?
