Legal alerts for a French company from BODACC, the official French gazette of legal notices: insolvency proceedings (procedures collectives) and related court filings, deregistrations and business sales, grouped and most recent first. Check whether a French company is subject to collective proceedings before you contract — a due diligence, KYB and compliance signal for supplier onboarding and risk monitoring, drawn from official registry data.

Credit risk scoring for a French company: a default-risk score (0-100) at ~12 months from a transparent scorecard — filed financial ratios (structure, profitability, liquidity, net cash, debt service, trend), company age, and a hard BODACC override (open insolvency/liquidation, or closure for insufficiency of assets). Returns the score, a qualitative band, every component with its threshold, and a confidence level. Decision-support indicator — NOT a solvency opinion or credit rating.

Reverse search for company directors and officers in France: a people search by surname (?nom=) that lists the French companies where a person of that name holds or held an office, with each company SIREN, name and the person role — network mapping and due diligence on directors. Person data is limited to surname, first names, role and birth YEAR (French GDPR/INPI rules). Results are indicative: homonyms are not disambiguated and very common names are capped.

Company lookup KYB — Know Your Business verification of a French company in one call: official company data for due diligence, compliance and customer onboarding: identity, officers, BODACC legal alerts (insolvency, deregistration), filed financials, sanctions screening of the company and each officer against the 6 official lists, computed VAT number and a completeness score. Per-block provenance: every block states its official register and as-of date.

Batch KYB and bulk company lookup: full Know Your Business files for 2 to 100 French companies in one call (comma-separated sirens parameter) — bulk due diligence, compliance and onboarding screening of a whole portfolio, each file with per-block provenance (official register + as-of date). Billed per company at $0.105 (30% off the $0.15 unit price); the amount is quoted from the number of SIREN. A SIREN with no diffusible company is returned as trouve=false and billed as one lookup.
