  title: Fortnite Tracker Challenges API
  version: '1.0'
  description: Fortnite Tracker (api.fortnitetracker.com/v1) is the Tracker Network developer surface that wraps Epic Games' Fortnite telemetry behind a simple REST API. It exposes per-player lifetime statistics, regional leaderboards, competitive power rankings, the daily/weekly in-game store rotation, and the current week's Battle Pass challenges. Every call requires a TRN-Api-Key header issued from fortnitetracker.com/site-api/create. The service is intentionally rate-limited (about one request every two seconds per key) and has been in a silent end-of-life state for several years — some endpoints may return intermittent errors.
