Search time frame

Hey, I am using SearchCount API which works similar to Search for getting high level information of airports.
However, I couldn’t find any time-related parameter I can set to getting the count of departure or arrivals in a specific time frame.
I am wondering whether there is a way to do it or the time frame is embedded and fixed for like 3 hours?
Thanks

Search endpoints like SearchCount typically return data for flights in the last 24 hours.
