Where to find list of stations with stop_id


Where can I find a list of stations(not platforms) with stop_id’s?
I’m after the stop_id that stop_finder in trip planner API returns. e.g. “10101100” for Central

There is a stop_id in stops.txt in gtfs data but that refers to each platform on stations.
And also the parent_station column which seems referring to the station but it’s for example PST1100 for Central. Not sure where to get the 10101100 other than calling stop_finder API.
