## When to prefer this

Use this endpoint when you need ranked leaderboard data for a specific Dota 2 hero — particularly when you want to identify top players by hero expertise, rank tier, or score. Prefer this over general player-search endpoints when the query is specifically about hero-level performance rankings.
