API for retrieval of AIS (Automatic Identification System) data. The data is provided by Kystverket. This is a json api for a subset of the data available in the AIS data.
Open AIS
Open AIS provides AIS data from sources from Kystverket. Coverage is best near the coast. Pleasure crafts under 45 meters and fishing vessels under 15 meters are not shown. Open AIS data is NLOD licensed.
OpenAPI documentation
You must register your application if you use the API: Application registration and authentication.
Restricted AIS
More coverage and smaller vessels are available in the restricted AIS streams. They require authentication with a user that has been authorized to access the data. The endpoints for restricted data are not documented here.
