OpenMeteo GmbH, Zwitserland (open-source weer-API, met modellen van onder meer KNMI, DWD en ECMWF)World, grid cell (2 km for the KNMI model, 9 to 25 km for the archive)
Open-Meteo turns weather models and reanalyses into one simple JSON API: hourly forecasts (for the Netherlands also the KNMI HARMONIE-AROME model at 2 km), and an archive from 1940 based on ERA5. You ask for a latitude and longitude, not a weather station. The data are CC BY 4.0, but the free API is for non-commercial use only and fewer than 10,000 calls a day. robots.txt on the API hosts disallows all bots, so the Open Data Index does not call Open-Meteo itself.
