  title: WeatherAPI Travel Briefing
  summary: Build a full travel briefing for a destination — current, forecast, astronomy, and alerts.
  description: >-
    A comprehensive destination briefing that chains the most useful WeatherAPI
    endpoints. The query is resolved through the search/autocomplete endpoint,
    current conditions with air quality are fetched, a multi-day forecast with
    pollen and alerts is retrieved, astronomy for the arrival date is added, and
    the dedicated alerts endpoint pulls any government warnings. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
