Rainbow Unified Weather API brings essential weather information together through a single developer-ready integration. It combines current conditions and standard meteorological parameters with Rainbow.ai’s high-resolution precipitation nowcasting and a weather forecast extending up to seven days.

Available parameters include actual and feels-like temperature, atmospheric pressure, humidity, wind, UV index, cloud conditions and precipitation data. The proprietary nowcasting component provides approximately 1 km² spatial resolution, is refreshed every 10 minutes and forecasts precipitation up to four hours ahead. The seven-day forecast adds the longer-range context required for planning, scheduling and user-facing weather services.

By consolidating real-time conditions, short-term operational intelligence and longer-range forecasts in one API, the product reduces the need to integrate and maintain several weather providers. It is designed for consumer weather applications, travel and outdoor platforms, mobility and delivery services, mapping products and other digital businesses that need broad weather functionality through a scalable integration.
