Translation
The *Strait of Hormuz* — corridor between Iran and Oman — carries ~20% of global oil daily. Sharp drops in transits often signal geopolitical tension before it hits the news. Data from *AIS* — the public broadcast every ship transmits with its position.

- AISStream.io (Phase 1: sample-only via Vercel cron)
- Cadence
- Daily
- Sensors / APIs
- AISStream WebSocket (sample-poll Phase 1)
- AOI
- Strait of Hormuz polygon — 26.5°N to 26.7°N, 56.0°E to 56.5°E
- Baseline
- Trailing 30-day mean
- Uncertainty
- Phase 1 sample-only ingest = ±10% count fidelity vs persistent WebSocket
- Known biases
- AIS class-B receivers spotty in the Gulf
- Sanctioned vessels often spoof or disable AIS
