# Initial National Demand outturn per day (INDOD) stream

`GET /demand/outturn/daily/stream`

This endpoint provides initial National Demand outturn daily data. The total daily energy volume is the total
demand volume for the previous day expressed on an initial National Demand outturn (INDO) basis, i.e. excluding
station transformer, pumping and interconnector export demand. It is calculated from summing the half hourly
INDO demands (divided by two to convert to MWh).
            
If no date window is chosen, the search will default to results from the last 31 days.

This endpoint has an optimised JSON payload and is aimed at frequent requests for the data.
