data type of display value of a column(not internal type) using rest api

[kanikag]

I want to retrieve the data type of column, not internal type. I know how to get internal type using sys_dictionary, I am looking for data type of column for example

state column in task table has internal type integer but display value is string(Open, closed)

I am looking for the type of display value, base_type perse. So basically for state I am looking for type of its display value which is integer. Internal_type is the type of actual value 1,2,3... display value for state is open, closed etc which is string
