From key to your first answer in about two minutes.

Get a keyRequest a free key. It starts with gw_live_ and goes in one header.

Make a requestSend it as Authorization: Bearer <key>. Try the waiting times at Rotterdam on the right.

Go furtherFollow a vessel's port calls, export a port's arrivals as CSV or pull port events into your systems.

Three questions to try

How long are tankers waiting off Rotterdam this week? Waiting times
Which vessels are arriving at Singapore and when? Port activity
Where has this vessel called in the last week? Port calls

For a client generator or an API tool: the OpenAPI file, without the live stream.
