Documentation
A bounded read profile: entity collections and identities, metadata navigation and one-level expansion, numeric observations, UTC time filters, counts and pagination. Observation expansion, nested expansion, writes, tasking and historical location reconstruction are unsupported. Public pages contain at most 1000 entities; refine time filters before exceeding offset 10000. Source-specific API publication remains governed by the public API catalogue.
