Per-state regular-grade averages plus a national mean computed across the 50 states + DC.

Querystates (1 / true to include the per-state list; default omitted for payload size)

The dashboard's authoritative throughput figure. Carries the per-type breakdown (tanker, cargo, container, dry bulk, general cargo, Ro-Ro), capacity in deadweight tonnage, the trailing 30-day rolling baseline median, and a separate pre-crisis baseline median (records before 2026-02-28) used as the stable peacetime anchor.

Side-by-side daily counts for Hormuz, Bab el-Mandeb, Suez, the Cape of Good Hope, and Malacca, sorted Hormuz first, then by nTotal / preCrisisBaselineMedian ascending so the most-disrupted route rises to the top.

Queryhistory (1 / true to include per-chokepoint daily history[])

Sum of "ships in port" plus 24-hour arrivals and departures across the five Gulf ports adjacent to the strait. Coarser than AIS but survives AISStream outages.

Sum of arrivals, departures, and "ships in port" across four South African ports (Cape Town, Durban, Port Elizabeth, Saldanha Bay). Tracks rerouting pressure as tankers avoid the Gulf.

Live counts at Fujairah, Sohar, Bandar Abbas, and Jebel Ali derived from AISStream positions inside a 10–12 km radius. Broken down by status (anchored, stopped, transiting) and vessel type.

Anchored + stopped count inside the Persian Gulf bounding box, hourly. Powers the homepage sparkline.

Querylimit (default 168 = 7 days hourly, max 720), since (ISO)

Hourly cross-tab of vessels in transit by AIS ship_type (tanker, cargo, military, other). Pairs with /api/v1/stranded for a full picture of the strait's vessel mix over time.

Querylimit (default 168 = 7 days hourly, max 720), since (ISO)

Tankers that have stopped broadcasting AIS inside the strait core area. Filters: type === tanker, totalSightings ≥ 50, last position in lat 24–28 / lng 55–58, last seen 3–24 hours ago. Strict, biased toward false-negatives. Multiple plausible causes (equipment failure, GPS spoofing, evasion, leaving bbox).

Vessels currently visible on AIS in the strait window whose names match an OFAC SDN entry. Match strategy: IMO when present, normalised name otherwise. False positives possible on common names; treat as indicative.

Per-vessel manifest compiled across the Gulf and Cape routes. Identity-only: no real-time lat/lng. Used as the fallback list when live AIS goes silent. ?flagged=1 returns the subset matched against the OFAC SDN list (IMO-based join).

Queryflagged (1 / true for OFAC-matched only), region (hormuz | cape), limit (default 500, max 500)

EIA/IEA shares of global seaborne oil and LNG that transit the strait, a curated estimate of the daily economic cost, the most-affected importing economies, and the extra voyage days of the Cape reroute.

Marine war-risk high-risk-areas designations as published in the industry circular, plus a flag noting whether the latest revision mentions the Arabian Gulf. Drives war-risk premium loads at most London-market underwriters.

Top global container carriers (ranked by TEU capacity) and their current posture: suspended, rerouting, limited, or transiting. Includes vessels-trapped count, combined trapped-TEU capacity, and the per-carrier surcharge in USD per TEU. ≥5 carriers suspended or rerouting drives the dashboard's "effectively closed" verdict.

Petroline (Saudi Arabia → Yanbu) and Habshan-Fujairah (UAE → Gulf of Oman) are the main lines that move crude out of the Gulf without transiting Hormuz. Each row carries nameplate capacity in BPD and current utilisation percent.

Sell/buy rates in both Toman (1 Toman = 10 Rial) and Rial, plus 24-hour and 7-day percentage deltas off the midRial.

JSON archive of every brief written by the dailyBrief Cloud Function, keyed by UTC date. Each brief carries 3–6 bullets, a short summary, the day's Brent price plus 24-hour delta, and the day's transit count.

Querydate (YYYY-MM-DD for a single brief; 404 if missing), limit (default 30, max 120)

Bare-minimum payload polled by the homepage ticker every 60 seconds: Brent price, 24-hour change, transit and stranded counts, plus a verifiedAt anchor.

Compares the current state to a caller-provided anchor timestamp. Returns a material flag once any of: ≥24h elapsed, |Brent %| ≥ 1, ≥1 event, ≥1 carrier posture change, |transit delta| ≥ 3, or |stranded delta| ≥ 5.

Queryat (required ISO timestamp)

Backed by EIA Weekly Petroleum Status Report. Carries the 4-week change so spike-vs-baseline reads correctly.

Cushing, Oklahoma is the WTI delivery hub. Inventory swings here track the North-American crude balance independent of the Gulf-Coast / SPR picture; pairs with the Brent–WTI spread to indicate whether disruption is global or American-specific.

Indexed strikes, ship incidents, closures, and negotiations. Mirrors the curated Firestore record so consumers see the same source attribution as the homepage timeline. Companion to /data/events.csv and /feed.xml.
