Retrieving all possible journeys for a given search independent of time

I want to retrieve all methods of getting between point A and point B regardless of when they arrive. So for example, I want to get both buses and night buses. I only need a single representative example from each method, and don’t care about when it comes, delays, etc.

Is there a way of doing this in a single request to the API, or would I have to just make multiple searches through the journey planner at different points throughout the day/night? E.g. at 0800, 1600 and at 2400.
