Sirenic
GET https://api.sirenic.eu/v1/recherche
French company search and company lookup by name or SIREN in the official French company registry (INSEE Sirene / INPI RNE open data). Name search returns the top 10 matches with identity, SIREN, NAF code, city and active/ceased status, plus a score_confiance (0-1 match confidence) that helps disambiguate homonyms. The entry point to official data and company data on France: resolve a trading name to its SIREN identifier before pulling the full company profile, filings or financials.
