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.

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.
