Maersk Container Tracking API & MCP

Query live Maersk (maersk) shipping container moves in a single synchronous GET request or MCP tool call. Pass the container number; no booking, bill of lading or Maersk account is needed.

Container Number Format & Auto-DetectionCopy Anchor Link

A container number is the owner's 4-letter code, 6 digits and an ISO 6346 check digit. Maersk's own owner codes detect to maersk automatically. A leased container (Textainer TGHU, Triton TCNU, CAI CAIU, SeaCo SEGU and others) can sail with any line, so pass ?carrier=maersk for one booked with Maersk.

NotesCopy Anchor Link

• Source: the JSON maersk.com's own tracking page receives. Akamai refuses that call from servers, so it is read through a browser session; one session serves a whole batch, and a lookup takes several seconds.
• Events: actual moves only (gate out empty, gate in full, loaded, vessel departed and arrived, discharged, gate out full, empty returned), each with the vessel and voyage where there is one. Planned moves are left out; the final ETA is estimatedDelivery.
• Times: Maersk gives each move's local time without a zone, so localTime is set and timestamp is null.
• Status: the empty box going to the shipper is label_created, the full box leaving for the consignee is out_for_delivery, and the empty coming back is delivered (the trip is over). Everything between is in_transit.
• Hamburg Süd (SUDU) containers are tracked on maersk.com and detect to maersk.
