  title: Shodan Historical Trends vs Live Exposure
  summary: Pull historical monthly trends for a query, then compare to the live count.
  description: >-
    A then-versus-now exposure pattern. The workflow runs a query against the
    Trends API to retrieve monthly historical counts and faceted breakdowns,
    then runs the same query against the live REST count endpoint so the current
    exposure can be compared to the historical trend. Both APIs use the same
    `key` query parameter. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
