  title: OpenWeatherMap Coordinate Weather And Air Snapshot
  summary: From raw coordinates, gather current weather, One Call current conditions, and air pollution.
  description: >-
    Builds a complete environmental snapshot for a known latitude and longitude
    by fanning out across three OpenWeather products. It reads the classic
    current weather endpoint, the unified One Call current conditions endpoint,
    and the current air pollution endpoint, then surfaces the most useful values
    from each. Every step spells out its request inline, including the appid API
    key the security scheme requires, so the flow can be read and executed
    without opening the underlying OpenAPI descriptions.

  summary: Gather current weather, One Call current conditions, and air pollution for a coordinate.
  description: >-
    Takes a latitude and longitude and reads three independent OpenWeather
    endpoints, returning a combined view of current weather, One Call current
    conditions, and air quality.
