Flag status reference
Mast answers a common question quickly: should a flag be at half-mast, half-staff, or full-mast today? The page shows the current status, the relevant authority, date range, and source when a known order is available.
The public API can also provide flag status data for websites, dashboards, signage, and small automations that need a simple JSON response.
