Build on the open platform

Everything you need to build on AsteriaStar: a read-only public API with a provenance envelope on every response, machine-readable graph exports, verifiable bulk downloads, and clear licensing. No auth, no rate limits, no write endpoints.

Quick start

OpenAPI 3.1 specMachine-readable contract for all 23 implemented endpoints.
API referenceEvery endpoint, its parameters, and an example.
Graph export (JSON)The whole typed graph in one document.
Graph export (JSON-LD)RDF-compatible, SPARQL-ready linked data.
Bulk downloadsReal SHA-256 checksums and sizes.
Sources & licensingCC BY-SA 4.0 + per-source terms.

The full platform

See the Open Astronomy Platform for every capability — including the architecture-ready SPARQL, GraphQL, SDK, DOI, and Virtual-Observatory interfaces, each described honestly. Provenance and quality are documented under source quality.
