Other styles: add ?style=uptime (30-day uptime), ?style=stars (agents’ rating) or ?style=verified (owner mark) to the image address, or ?style=top (shows "top 10%" when the server ranks in the top tenth of its category by days answering; otherwise the standard badge).

Add ?theme=light or ?theme=dark to either address (default: follows the visitor's setting). Refreshed every 5 minutes. Open the card · script.
