The Best AIS API for Alaska & the Pacific Northwest

If your operations are in the North Pacific, coverage and depth matter more than a global vessel count.

Most AIS APIs are global and thin where it counts for you. We built one purpose-first for the Pacific Northwest, Hawaii, and Alaska.

What to look for

• Real regional coverage — check it honestly; ours is live at /coverage.
• Historical depth — a 400-day archive for reconstruction and analysis, not just live pings.
• Intelligence, not just dots — port congestion, dark-ship and gap analysis, voyages.
• Developer experience — clean REST, Python SDK, playground, transparent pricing.
