post/weather-intel/v1/historical2 credits

Historical weather (Open-Meteo Archive / ERA5 reanalysis, 1940→present, free/keyless) for a coordinate and date range: daily aggregates (min/max temp, precipitation, wind, weather-code, sunrise/sunset) and/or hourly variables. The live forecast actions exclude history — this is the long-record companion. Default daily set is returned when neither 'daily' nor 'hourly' is specified.
