How It Works

  1. Fetches the Top Free overall chart from Apple RSS for the specified country (up to 200 apps).
  2. Each app’s primary genre is determined from its iTunes metadata.
  3. Apps are grouped by genre, and the highest-ranked app in each group becomes the category’s #1.
  4. Results are returned as a flat list — one app per category.
reachedAt is always null currently. Determining when an app first reached #1 would require storing historical chart snapshots and comparing them over time. This feature is planned for a future release once daily chart tracking is implemented.
Use this endpoint to monitor category leaders and spot emerging trends. If a new or unexpected app appears as #1 in a category, it may indicate a viral moment, seasonal trend, or major marketing push.
