BOUNDARIES
Read the limits
- Current observations must not be replayed or interpreted as a historical trend.
- Absence from a sample is not proof of departure, non-arrival, or disruption.
- No named route is inferred from vessel proximity or a single current position.
Require an authorized server-side account and present sampled coverage as incomplete current observations.
PROVENANCE
Source and rights
account-backed access; keep the API key server-side and preserve source attribution; authorized bulk imports remain separate historical AIS sources
