To query a forecast, use the following python code:

import requests
import pandas as pd

site_id = 'Put the site ID here' 
 
url = f'https://api.rebase.energy/platform/v2/sites/{site_id}/forecast'

start_date = pd.to_datetime('2024-06-28T06:15').strftime('%Y-%m-%d %H:%M')
end_date = pd.to_datetime('2024-06-28T07:15').strftime('%Y-%m-%d %H:%M')
ref_time = pd.to_datetime('2024-06-28T00:00').strftime('%Y-%m-%d %H:%M')
tz = 'UTC'

params={
	'start_date': start_date,
	'end_date': end_date,
	'ref_time': ref_time,
	'tz': tz
}

response = requests.get(url=url, headers=headers, params=params)
response.raise_for_status()
response = response.json()
