  title: Rainbow.AI Tiles API
  description: >-
    The Rainbow.AI Tiles API provides global cloud coverage map tiles with
    high-resolution weather visualization data (256x256 tiles) delivered via
    XYZ CDN. Supports real-time and forecasted precipitation layers, updated
    every 10 minutes. Ideal for map-based applications, dashboards, and
    spatial interfaces.

      description: >-
        Returns a 256x256 PNG weather map tile at the specified zoom level and
        tile coordinates using the XYZ tiling scheme. Tiles show precipitation
        forecasts and can be overlaid on any mapping library (Leaflet, Mapbox,
        Google Maps, etc.).
