Weather — entry 022 of 31
Rainbow Weather
Rainbow.ai runs a Nowcast API that returns minute-by-minute JSON precipitation-rate forecasts for the next 4 hours, plus a Tiles API serving 1km-resolution XYZ PNG tiles (precipitation, clouds, radar) compatible with Mapbox, Leaflet, Google Maps and Cesium. Coverage is global with updates as frequent as every 1-10 minutes via CDN, billed metered pay-as-you-go beyond a free monthly quota (roughly 5,000 nowcast / 30,000 tile calls).
