  title: WeatherAPI Current and Forecast Air Quality
  summary: Resolve a location, then fetch current and forecast weather with air quality and pollen enabled.
  description: >-
    Surfaces the WeatherAPI air-quality and pollen data that rides alongside the
    weather payloads. The query is resolved with autocomplete search, current
    weather is fetched with the AQI flag enabled to read live air quality, and a
    forecast is fetched with both AQI and pollen flags enabled for forward
    looking exposure planning. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
