Execute Weathernext Point Forecast V1

by Macaroon Network in Weather & location

x402 APIPassing, checked 55 min ago

Point-location weather forecast/reanalysis lookup from Google DeepMind's WeatherNext model via Earth Engine. Every request is bounded to data at least 1 hour old -- the exact license boundary at which WeatherNext data becomes CC BY 4.0 and commercially reusable. This listing never serves data still under the real-time Terms of Use, which explicitly prohibits commercial resale.
