Calculate sea-route voyage distance and vessel ETA using the Searoutes API

Steps
Register for a Searoutes account and obtain an API key via the developer portal.
Call the sea route endpoint with origin/destination as coordinate pairs (longitude,latitude) or UN/LOCODEs, plus your API key, to get distance and duration.
Optionally add up to 18 waypoints or chain multiple legs in one request for multi-port voyages.
Call the vessel ETA endpoint with an IMO number to get an AIS-informed ETA prediction, current speed, draft, and last position.
Parse the response for distance (meters), duration (milliseconds), and any traffic-separation-scheme/canal routing notes.
Known gotchas
Coordinate order is longitude,latitude (not the more common lat,lon) - a swapped pair silently produces a nonsensical route.
ETA predictions rely on live AIS coverage for the vessel - poor AIS visibility (e.g., mid-ocean gaps) degrades prediction accuracy.
Free-text port names aren't accepted directly - use UN/LOCODEs or coordinates, so a separate port-lookup step may be needed.
