Data Sources & Attribution

Every fact, figure, and entity on 4ort.xyz comes from open data sources we cite below. We blend CC0 datasets with US Federal public-domain APIs to build a knowledge graph for AI agents. No scraped private content, no proprietary feeds, no licensing surprises.

Architectural principle: Wikidata is our source-of-truth for entities. Federal APIs (BLS, BEA, Census, EIA, Treasury, FRB) supply economic indicators. SEC EDGAR provides corporate filings. Wikimedia provides imagery. Each layer is open or government public domain — every redistribution is legally clean.

⭐ Sources that create entities (75 live)

These datasets mint rows in the graph. Every entity records which one created it, and that source's licence is returned with the entity through the API.

🛰️ News-derived layer (inferred, labelled, never mixed with CC0)

Entities and facts we derive from news coverage rather than import from an open dataset. They live in a separate inferred layer with their own trust labels, and every one carries the source URLs it was derived from. Nothing here is presented as Wikidata-grounded.

GDELT Project (GKG + Event database) Open data, attribution required ↗

License: Open data, attribution required · Ingest: GDELT 15-minute global news feed · Attribution required
Use: News-derived entity discovery (the Living Edge frontier), country stability signals and recent-article matching. Entities minted from GDELT are stored in the inferred layer, never mixed into the CC0 Wikidata-grounded layer.
Requires >=2 independent publishers before an entity or fact is minted.

Press-release wires (PR Newswire, Business Wire, GlobeNewswire) First-party corporate statements (facts, attributed) ↗

License: First-party corporate statements (facts, attributed) · Ingest: Public RSS feeds + syndicated release pages · Attribution required
Use: Product and company facts extracted from press releases. Facts sourced only to the subject's own release are labelled `vendor_claimed` and never presented as independently verified; a second independent publisher promotes them to `corroborated`.
Extraction is local (GLiNER/Relex), batch-only — never in a request path.

🔒 Licensed, internal use only (never redistributed)

We license these for internal ranking and prioritisation. They are not published on any page, not returned by any API, and are not part of the redistributable dataset. Listed here because complete provenance means listing what we use, not only what we publish.

License: Commercial licence — internal use only · Ingest: Licensed commercial API · Not redistributed
Use: Search-volume and CPC data licensed for INTERNAL ranking and prioritisation only. It is never published on any public page, never returned by any API response, and is not part of the redistributable dataset.
