Developers

Asteria Star is designed to be consumed by applications, researchers, and AI. The read-only Open Data API v0 is live today; broader API surfaces are planned and clearly labelled.

Open Data API (v0)

Implemented

Read-only, deterministic, engine-backed JSON. 134 datasets are catalogued; every response is a projection of the knowledge graph.

Planned API surface

Planned

Designed, not yet implemented. Listed for transparency and never exposed as fake endpoints.

  • Timeline API

    Curated, sourced chronologies.

  • Comparison API

    Compare two entities or concepts.

  • Discovery API

    Graph-derived recommendations for an entity.

  • Learning Path API

    Structured learning journeys.

  • Live Sky API

    Real observational data — once a provider is connected and its licensing verified.

Citation engine

Reusable citation formatting generated from structured metadata — never fabricated. One real reference, every supported style:
