Maersk's own data is already structured. Most teams still re-key it by hand.
Maersk runs one of the most extensive carrier developer portals in the industry, exposing dedicated API products for Track and Trace, DCSA-aligned Ocean Booking, Schedules, Product Offers and pricing, electronic Bills of Lading, Verified Gross Mass, and Demurrage and Detention. That data is already structured and ready to consume, but it only helps if it reaches CargoWise automatically instead of getting checked separately on Maersk's own tools.
Because many of Maersk's APIs follow Digital Container Shipping Association (DCSA) interface standards, the same integration approach carries over cleanly if you ever need to connect additional DCSA-aligned carriers later, this isn't a one-off, Maersk-only build.
