API routine in Python to retrieve Bus Frequencies

There must be a routine similar to the ones to retrieve bus voltages, branch currents and generator real powers, right? I know that in the GUI, one can set channels for BsFreq and use the frequency values obtained in the output files. Just looking for something along the lines of:

ierr, bus_voltages = psspy.abusreal(-1, string = "PU") // API command to retrieve bus voltages

Those API's are returning steady state values, i.e. from load flow calculation. In load flow the frequency is always nominal (50 or 60 Hz). Hence, there is no API to return the frequency.

Bus frequency can only be retrieved with a channel when performing dynamic simulations.
