  title: WeatherAPI Historical Weather
  summary: Resolve a location, then fetch historical weather for a past date.
  description: >-
    Pulls observed weather for a date in the past. A free-text query is resolved
    through the search/autocomplete endpoint, and the history endpoint returns
    the hourly and daily breakdown for the resolved location on the requested
    date (on or after 1 January 2010). Every step spells out its request inline
    so the flow can be read and executed without opening the underlying OpenAPI
    description.
