Patrick did include a way to exclude DIFF and STEP mags from the API call. It is with this parameter: &where=mtype%3D0+or+mtype+is+null (note that STD obs have mtype = 0 or mtype = null)
Please remember that observations with mtype = null should be treated as mtype = STD so don't forget to include them!
Thanks Sara.
