This viewer calls the real collector API: GET /v1/stats/overview (read KPIs) and POST /v1/events (push an event). Because the API checks the Origin header, this page must be served from harpd.com (or localhost); opening it as a file:// will be blocked by CORS. A valid API key is required — without one the API returns 401 unauthorized. You can also open this page directly from your Harpd account with the key already filled in.
