This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
Aalyria Technologies builds software and hardware for operating resilient, high-throughput networks in motion across space, air, land and sea. Its flagship platform, Spacetime, is a temporospatial software-defined networking system that models the time-dynamic position and orientation of satellites, aircraft, ships and ground stations, then continuously plans, schedules and steers the links between them. Aalyria also produces Tightbeam, a free-space optical communications system. The company was spun out of Alphabet in 2022, carrying technology developed for Project Loon and Taara.

Spacetime has no OpenAPI, no GraphQL and no REST surface. The machine-readable contract
is proto3 + gRPC, published openly under Apache-2.0: 45 .proto files, 13 services,
182 RPCs, 512 messages, harvested verbatim into grpc/ with the upstream api/
layout preserved so import paths resolve.
Three interfaces:
| Interface | What it does |
|---|---|
| Northbound (NBI) | Define and orchestrate the network — Model (NMTS entities/relationships), Provisioning (SR-TE policies, links, downtimes, constraint groups), Solution (computed beams and paths), Simulation, Permissions, Audit |
| Southbound (SBI / CDPI) | Device-facing control plane — a long-lived bidirectional ReceiveRequests stream carrying beam/radio/flow control updates, plus ExportMetrics telemetry push |
| Federation (East-West) | Inter-operator interconnection and transponded capacity, in the community outernet.federation.* namespace rather than Aalyria's own |
Instances are deployed per customer on a customer-specific $DOMAIN, resolved by
subdomain (model-v1.$DOMAIN, provisioning-v1alpha.$DOMAIN, status-v1.$DOMAIN).
Authentication is a self-signed RS256 JWT whose aud claim is bound to a single gRPC
service and method — there is no OAuth and no shared production host.

AsyncAPI, a public status page, public pricing, self-serve sign-up, a hosted MCP server, a
Postman collection, a vulnerability disclosure policy, and a trust center. Spacetime is sold
and deployed under commercial agreement, so credentials are issued out of band. Instance
health is exposed programmatically instead, through StatusService.GetVersion /
GetMetrics (OpenTelemetry format).
Spacetime also publishes no idempotency contract — no idempotency key, no client token,
no request-deduplication guarantee on any write RPC. The nbictl ... sync flow is a
client-side convergence loop, not a server-side guarantee.
