Anemlo API

Weather data with a credit line, not a contract.

Start free with US weather from the NWS public domain. Move up for global data, the Wire, tropical tracks, tides, and AI signals. Keys are self-serve, and the free tier needs no card.

Authentication

Send your key as X-Anemlo-Key. Never put keys in query strings — they leak into logs, referrers, and caches.

Free tier is US-only because NWS data is public domain. Global data (Open-Meteo) ships on Pro under a commercial licence. Anemlo is not an official weather source.
