Vessel API

The Future of Maritime Communication

The Vessel API is more than just a data interface—it's a live link between ship and shore. Built on GraphQL, it enables real-time access, insight, and interaction with your fleet like never before.

Two-Way Communication with Your Crew

Seamlessly connect your planning, billing, and voyage management systems with the Onboard Vessel API to streamline operations across your fleet.

Planned voyages are delivered directly to the crew via the Ship App, complete with notifications and all relevant details. As the voyage progresses, real-time updates flow back to shore—keeping you informed, improving coordination, and enabling immediate action.

Say goodbye to manual steps—and hello to a fully connected, data-driven operation.

Voyage API

Our integration with Onboard is the easiest and fastest integration that I've worked on. The choice of GraphQL is great because it means the API is essentially self-documenting, and that really high-quality interactive documentation means you can be almost certain that whatever you've coded will work before you even hit send.

The Power of Combining Ship and Crew Data

The Vessel API gives you unified access to raw sensor data from onboard systems and crew-entered registrations—available separately or combined into rich, contextualized reports.

This complete picture gives you the operational insights needed to improve efficiency, reduce costs, and ensure compliance. From equipment activity and fuel consumption to crew-logged delays and performance notes—it’s all connected, all available, and all yours to use.

Everything You Need in One API

Whether you're building advanced analytics, automating workflows, or simply keeping a pulse on daily operations, the Vessel API makes it easy.


  1. Fully Documented and Developer Friendly

    Everything you need to know can be found in the API itself. The types of data you can collect, queries and mutations you can make, all in a format that both humans and machines can understand and anyone with a little training can learn.

  2. Get Exactly What You Need

    Query only the data you want—no more overfetching or underfetching. Whether it’s just the thruster RPM or a full contextual voyage report, you’re in control.

  3. Built for Complex Real-World Use Cases

    Complex relationships between vessel systems, crew activities, and voyage timelines are easy to model and query. Want fuel consumption during docking, per terminal? Easy. Even better—visualize it instantly in the integrated dashboarding tool.
