Spacetime Northbound Interface (NBI) is one of 4 APIs that [Aalyria](https://apis.io/providers/aalyria/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Orchestration, Networking, Provisioning, Modeling, and gRPC. The published artifact set on APIs.io includes API documentation and a getting-started guide.

The Northbound Interface allows humans or applications to define and orchestrate a Spacetime network. It carries the Model API (NMTS entities and relationships describing platforms, antennas, interfaces and their time-dynamic position and orientation), the Provisioning API (traffic-engineering policies, links, downtimes, protection and disjoint association groups, geographic regions), the Solution API (computed beams and candidate paths), the Simulation API (scenarios and analyses), Permissions and Audit Logs. It is a gRPC API defined in Protocol Buffers and served per customer instance over subdomain-resolved endpoints such as model-v1.$DOMAIN.
