  title: Last.fm Geo Artist Spotlight
  summary: Find the top artist in a country, resolve their full profile, and list their top albums.
  description: >-
    A localized spotlight flow that surfaces what a country is listening to. It
    reads the most popular artists for a given country, takes the leading
    artist, resolves their full profile, and lists their top albums for a
    ready-to-render spotlight. Each request is written inline, including the
    required api_key and the format=json selector, so the flow is self-contained
    and replayable without the OpenAPI source.
