Public data access

Use the observatory data directly.

Public-interest exploration needs the underlying data to be inspectable. These JSON and CSV endpoints expose the same public records that power profiles, rankings, reports, and the evidence ledger.

Observatory relationship atlas

Exact declared links among institutional research topics, public research questions, competition issue programs, markets, source-labeled products, official operators, Census screens, national, state, and source-specific local places, indicators, enforcement records, named organizations, publications, and public sources. The ontology filter returns all 38 canonical relationship definitions, relationshipType returns a complete type-specific dossier, and edgeType filters a focused neighborhood, topology, diagnostics, ledger, ranking, or export to one canonical semantic contract. The rankings filter returns the complete profile population ordered by declared links, unique counterparties, partner-family breadth, or source-bearing links while preserving zero states. The matrix filter returns all 91 possible family contracts with active, other-layer, and never-encoded states. Complete family profiles use the family filter with separate profiles or relationships tables. Complete family-pair contracts use the pair filter, focused neighborhoods use focus/depth filters, bilateral packets use left/right filters, and multi-profile workspaces use two to six comma-separated items. No inferred ownership, equivalence, liability, control, economic importance, legal market, or causality.

Observatory relationship atlas declares source custody in its endpoint contract.

Observatory relationship atlas has no shared market-report parameter.

Open data needs public interpretation.

The API is a starting point, not a legal conclusion. Pair downloads with methodology notes, source records, and the data-gaps report when citing market concentration.
