Sirenic
Industrial risk and environment profile of a French company from the official ICPE register (Géorisques/DGPR): classified facilities with Seveso status (upper/lower tier), authorisation regime, activity state, IED flag, nomenclature rubrics and a risk synthesis per SIREN — an ESG and environmental compliance signal on hazardous sites operated by the company. A company with no classified facility returns level aucun (still 200) — the clean answer is the signal.

Availability API
Check a medication's availability before your agent orders or substitutes it: shortage reports from the French ANSM (data.ANSM) by CIS code or substance (INN/DCI) - status (rupture, risque_rupture, tension, remise_a_disposition, arret_commercialisation, or no_known_shortage), report dates, expected return and the official ANSM report URL. Honest by design: ANSM only records reported shortages, so the absence of a report is never a stock guarantee. French market scope: a US NDC key returns an honest FR-only coverage note.
