How Mast works
Mast is an informational flag-status tool. It helps answer whether a U.S. flag should be flown at full-staff or half-staff, why the order is active, and where to verify the official source.
Checks public orders
Mast watches federal and state flag-status sources for half-staff orders, observances, and official notices.
Normalizes the details
Each detected order is organized by location, authority, start date, end date, and source so the current status is easier to read.
Shows the source
Mast is informational, so active orders include a source link when available and should be verified with the official notice when it matters.
Explains half-staff
Half-staff means lowering the flag below the top of the staff as a sign of mourning, remembrance, or honor for the period named in an official order.
Mast API
Power badges, dashboards, and signage with current half-staff status.
Current status
Return whether flags are currently half-staff or full-staff for a selected jurisdiction, including the authority, active order, official source link, and timing Mast is using.

Oklahoma flag sources and verification
Mast tracks current federal flag orders and known Oklahoma local orders so residents, public buildings, schools, businesses, and local websites can quickly check whether flags should be at half-staff or full-staff today.
The Oklahoma source in Mast is Oklahoma Governor / oklahoma.gov, categorized as Official Governor Status And Newsroom. Oklahoma has an official source Mast can check for current flag status. Mast also uses the source to track historical Oklahoma half-staff notices when dated orders are available.
Oklahoma publishes the active flag status and temporary order details on the Governor's dedicated flag-status page. Mast treats that page as the authoritative current-status source and retains an observed event when it reports half-staff so ephemeral order details are not lost when the page returns to full-staff. Dated Governor newsroom directives remain available for historical event windows.
Flag status reference
Mast answers a common question quickly: should a flag be at half-staff or full-staff 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.
