Leadgen — Romanian ONRC Business Registry (API + MCP)
Free, read-only access to Romania's official business registry (ONRC):
every registered company, its CAEN activities, legal representatives, status,
and 2025 financial statements — built from the state's own open-data dump and
exposed over a tiny HTTP API and an MCP server.
- 4,196,860 companies
- 19.3M CAEN activity records
- 3.68M legal representatives
- 4.64M status entries
- 2025 financial statements loaded

Where the data comes from
The registry is built from the official ONRC snapshot published on
data.gov.ro — no scraping, no third-party vendor. The
loaders stream the CKAN CSVs into SQLite and build an FTS5 full-text index
with diacritic-insensitive folding, so popescu matches Popéscu and PAVĂL
matches paval.

Notes on the data
- Diacritic-insensitive search — Romanian
ă â î ș ț are folded to their
ASCII forms on both the index and the query.
- CUI vs registration code — a numeric
query is matched against the CUI
(tax code) first, then the registration code.
- Read-only — the public surface only exposes lookups; there are no write
paths.
