we use the historical pricing API end point to download historical data, e.g. for the future DEBMN6 the URL is
https://api.refinitiv.com/data/historical-pricing/v1/views/events/DEBMN6?eventTypes=trade&end=2026-04-15T12:50:56.093884Z&count=10
however, this doe not work with a freight RIC e.g. DFRT-ME-SIN is there a reason why?
