  Open-Meteo is an open-source weather API that provides free global weather
  forecasts, historical reanalysis data, marine conditions, air quality indexes,
  and long-range climate projections through a simple REST interface requiring
  no API key for non-commercial use. The service aggregates data from over 30
  weather models provided by 15+ national meteorological services including
  ECMWF, NOAA GFS, DWD ICON, Météo-France, and JMA, delivering resolutions
  from 1 km to 11 km updated every 1 to 6 hours. Historical data extends back
  to 1940 via ERA5 reanalysis, giving developers and researchers access to
  consistent long-term climate records alongside real-time forecasts. Commercial
  users who need dedicated server capacity, higher throughput, and access to
  extended APIs such as ensemble forecasts, seasonal outlooks, satellite
  radiation, and climate change projections can subscribe to paid plans priced
  at a flat monthly rate with no per-call overage charges. The entire server
  infrastructure is open-source under the AGPLv3 license and can be
  self-hosted, while the underlying weather data is released under CC BY 4.0.
