Are reported pressures generally local station pressures or sea level corrected pressures?

I anticipate sea level corrected pressures for "professional" weather stations. How certain can I be of expecting sea level corrected pressures from personal weather stations?

It seems, the WUnderground API returns sea level pressure (it is the same as at METAR)

that is what i understand is happening with my acurite pws on the api: wunderground does not publish sensor reading, but apparently normalizes to sea level at 20 celsius.

Hello WU, any possibility of publishing raw data?
