Unified API

A free lookup and JSON API for the IACS Vessels in Class dataset. Enter a ship's IMO number to see its classification society, class status (in class, suspended or withdrawn), last and next survey dates, and why its status last changed. IACS only publishes this as a ZIP/CSV download; we refresh it weekly. Check up to 100 ships per request, or ask Claude through our MCP connector. Try it, no signup: vesselclassfinder.com/?imo=9811000. Free: 100 lookups/month, paid from €49.

Hi, I'm Konstantinos from WeAreFabbrik, a small software company in Greece. IACS publishes which ships are in class only as a ZIP of CSV files, so checking one ship (or 200) means downloading and searching a file. So we load that dataset every Sunday and serve it by IMO number: class society, status (Delivered, Reinstated, Reassigned, Suspended, Withdrawn), survey dates and the reason for the latest status change. Three ways to use it: - a free lookup box on the homepage, no signup - a JSON API, up to 100 IMOs per request (free tier: 100 lookups/month, paid plans from $49) - an MCP server, so you can ask Claude "Is IMO 9321483 in class?" directly Limits: it's IACS's public data, not a replacement for class certificates, it covers only the 12 IACS members, and it refreshes weekly. The code is open source. What would you want next?

Update since launch: you can now try it without an account. This link opens the Ever Given's class status straight away: vesselclassfinder.com/?imo=9811000

Swap the number for any IMO you care about. If you check ships for chartering, vetting, insurance or KYC, I'd like to hear what's missing.

What do you check before fixing a ship? Launching a class-status lookup on Tuesday

Hi all, Konstantinos here (Greece).

On Tuesday we launch Vessel Class Finder: a free lookup and API for the IACS Vessels in Class data. You enter an IMO number and get the classification society, class status (in class, suspended, withdrawn), survey dates and why the status last changed. IACS only publishes this as a ZIP/CSV download.

Two questions for anyone in chartering, vetting, KYC or marine insurance:

When you check a vessel's class today, where do you look and how long does it take?
