The public Graph API
The public read-only REST API over the whole knowledge graph — entities, relationships, search, neighbourhood traversal, shortest paths, sources, and citations. Every response carries a provenance envelope; no auth, no rate limits, no write endpoints.
Citation Export
Available nowAPA · BibTeX · RIS
The real, source-backed citations behind entities, served as an API and exportable in APA, Chicago, MLA, Harvard, BibTeX, and RIS through the platform's citation engine. Every field comes from a verifiable citation record; none is invented.
/api/v0/citations →Neighbours & Evidence Paths
Available nowREST / JSON
The graph query surface: breadth-first neighbourhood traversal and shortest evidence paths between two entities, cycle-safe and bounded. The same real algorithms behind the graph explorer and the grounded assistant, exposed as an API.
/api/v0/traversal →OpenAPI Specification
Available nowOpenAPI 3.1
A machine-readable OpenAPI 3.1 description of every implemented endpoint, generated from the endpoint registry — so a client, a code generator, or an agent can discover the API automatically.
/api/v0/openapi.json →Public Graph API
Available nowREST / JSON
A read-only, deterministic REST API over the whole knowledge graph — list and fetch entities, list relationships, search, and traverse neighbourhoods and shortest paths. Every response carries a provenance envelope (version, source, licence, attribution). No auth, no rate limits, no write endpoints.
/api/v0/entities →Sources API
Available nowREST / JSON
The registry of authoritative sources behind the platform — every source's name, organisation, canonical URL, licence, and scope — served as a public endpoint, so the provenance of any cited fact can be resolved programmatically.

The full machine-readable contract is the OpenAPI 3.1 spec, and the reference lives at /developers/api.
