openSenseMap vs US Weather
openSenseMap is the open, non-profit citizen-science platform behind the University of Munster's senseBox project, serving live and historical readings from thousands of crowdsourced environmental sensor stations worldwide, covering not just temperature/humidity but also particulate matter, noise and other phenomena. Reading data is fully open and keyless (accounts are only needed to register or post data from your own senseBox), and the full historical archive is separately mirrored on an archive subdomain.
The National Weather Service API serves official US government forecasts, active alerts, and observation-station data as GeoJSON and JSON-LD feeds, with no signup or API key required. It's widely used by third-party weather apps and accepts direct browser calls, though it requires a descriptive User-Agent header identifying your application on every request.
