Real-time weather monitoring, lightning detection and severe-weather alerting.
The FLASH Weather API provides programmatic access to lightning detection, hail analysis, point forecasts, air quality and agronomy data. Every endpoint in this reference is callable from the page it is documented on, open an operation and use Send Request.
The playground targets the same origin these docs are served from, so requests from
app.flashweather.ai/docs/ hit the app.flashweather.ai API. No CORS setup, no proxy.
