POST/v1/bodacc/recherche
base$0.0300

Search French BODACC legal announcements by CRITERIA, not by company: pick a family (insolvency proceedings, deregistrations, sales, incorporations, accounts filings, conciliation...), a date window and optionally a department. Answers questions like: which companies entered insolvency proceedings in department 59 this week? Up to 100 announcements, newest first, each with its SIREN, court, town and structured judgment. Sole traders are excluded (their name is personal data) and counted.

POST/v1/comparer
base$0.1200

Company comparison: compare 2 to 5 French companies side by side in one call on official company data — identity, deterministic default-risk score, latest filed accounts (statutory scope) and BODACC insolvency alerts. Benchmarking for supplier selection and vendor shortlist: per-axis rankings, never an overall winner, plus a comparabilite block that flags NOT comparable companies (different sectors, sizes, a holding in the batch). Billed PER COMPANY: signed quote = $0.12 x number of SIREN.

POST/v1/dirigeant/recherche
base$0.0200

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.

POST/v1/documents/%7Btype%7D/%7Bid%7D
base$0.1000

PDF download of official documents from the French INPI RNE registry: retrieve the original filed document by type (actes | bilans) and document ID from the document list endpoint — legal deeds such as statutes and general-meeting minutes, or filed annual accounts. Typical size 1-10 MB, streamed as-is from the registry at request time; response is application/pdf. The primary-source evidence for due diligence on a French company: the actual deed or annual-accounts filing, not a summary.

POST/v1/entreprise/%7Bsiren%7D
base$0.0050

Full French company profile by SIREN: official company data from the French company registry (INSEE Sirene / INPI RNE). One company lookup returns legal name, legal form, head-office address, NAF code, workforce bracket, creation date, active or ceased status, officers with name and role, collective agreement and the computed intra-EU VAT number. The core KYB building block for verifying a French counterparty: registry facts for due diligence, compliance and onboarding checks.

POST/v1/entreprise/%7Bsiren%7D/agrements
base$0.0200

Regulatory authorisation and licences held by a French company, by SIREN: payment institution, e-money institution, account-information provider, payment agent or exempt entity from the EBA PSD2 register (daily), insurance undertaking from EIOPA, telecom operator (electronic-communications operator, ARCEP). Returns authorisation dates, licensed PSD2 services, EEA passporting and withdrawals — a compliance check across three official registers. Not authorised is a paid answer too (200).

POST/v1/entreprise/%7Bsiren%7D/alertes
base$0.0100

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.

POST/v1/entreprise/%7Bsiren%7D/capital
base$0.3500

Ownership and share capital structure of a French company from the official INPI registry: AI extraction of the latest PUBLIC articles of association filed at INPI — share capital amount, legal form, shareholders (name, role, birth YEAR, ownership %), notable clauses, with a confidence level and the source document reference. Due diligence from public filed deeds — NOT a beneficial-ownership register (RBE) and not a beneficial-owner identification. Immutable document: extracted once, cached.

POST/v1/entreprise/%7Bsiren%7D/changements
base$0.0100

Company changes monitoring for a French company: the new official BODACC gazette announcements published SINCE a given date (?depuis=YYYY-MM-DD) — the poll endpoint for watchlist and portfolio surveillance. Returns the new announcements (insolvency, deregistration, sales, filings, changes) in reverse-chronological order. Note: detects new BODACC publications, not field-level edits of the Sirene/RNE profile (the monthly stock keeps no history).

POST/v1/entreprise/%7Bsiren%7D/documents
base$0.0200

Official filings of a French company at the INPI RNE registry: lists the legal deeds (statutes, general-meeting minutes, mergers...) and filed annual accounts, with filing dates and the document IDs needed to download each PDF from the document endpoint. Only documents the registry marks as public are listed. The starting point for document due diligence in France: see which official documents, deeds and annual-account filings exist before paying to download one. Cached 24h.

POST/v1/entreprise/%7Bsiren%7D/dossier
base$0.0050

Full French company file in ONE call: identity is the base, then add the blocks you want and pay only for those — etablissements, alertes_bodacc, finances, marches_publics, marches_publics_ue, lobbying, risques_industriels, agrements, pi, documents, facturation_prep, score. Example: blocs=finances,pi,score on siren 552032534. Each block costs what its own endpoint costs, total capped at $0.35. A block that cannot be served is NAMED with its reason: no data, not disclosable, or upstream outage.

POST/v1/entreprise/%7Bsiren%7D/etablissements
base$0.0030

All establishments (SIRET) of a French company: the complete list of business locations registered under one SIREN, official data from the French company registry (INSEE Sirene), head office and branches alike, each with its address and open or closed status. Use it to map the branches and addresses of a company across France, or to check whether a given SIRET is still open. The SIREN identifies the legal entity; the SIRET identifies each of its establishments.

POST/v1/entreprise/%7Bsiren%7D/facturation-prep
base$0.0200

Supplier onboarding: PREPARE a compliant French e-invoice under the e-invoicing mandate France September 2026 (reception obligatory for every VAT-liable company; issuance phased GE/ETI 2026, SME 2027): legal name & form, status, computed intra-EU VAT number (with VIES pointer), establishments (SIRET) with addresses, NAF code, indicative obligation dates. Preparation only - Sirenic is not an accredited platform (PDP), never accesses the central directory and never issues or routes invoices.

POST/v1/entreprise/%7Bsiren%7D/finances
base$0.0100

Financials of a French company from annual accounts filed at the INPI registry, with Banque de France ratios: revenue, EBITDA, net income, debt ratio, financial autonomy — one entry per fiscal year. Includes the full structured financial statements line items (liasse fiscale tax form, incl. balance sheet) as keyed by INPI, for up to the 20 latest fiscal years. A perimetre_comptable block states whether figures are statutory or consolidated, and flags series where the source conflates the two.

POST/v1/entreprise/%7Bsiren%7D/lobbying
base$0.0100

Lobbying and influence profile of a French company from the official HATVP register of interest representatives — a transparency, governance and ESG due diligence signal: registration status, category, lobbying-expense brackets per fiscal year, staff count, recent subjects with intervention domains and action types, clients (for consulting firms), affiliations, declaration defaults and deregistrations. Organisation-level only — no personal data. Not registered is a meaningful answer (still 200).

POST/v1/entreprise/%7Bsiren%7D/marches-publics
base$0.0100

Government contracts and public procurement awards won by a French company, from the official DECP open data (données essentielles de la commande publique): buyers, amounts, dates and procedures — aggregates plus the most recent contracts. Covers French public tenders already awarded to the company rather than open calls, a factual view of its government contracts history for supplier due diligence.

POST/v1/entreprise/%7Bsiren%7D/marches-publics-ue
base$0.0200

European public procurement contract awards won by a French company, from TED (Tenders Electronic Daily, EU Publications Office): government contracts and tenders — buyer, country, subject, notice-level amount, CPV codes, co-winners and official notice link. Identifier-based matching only (SIREN/SIRET incl. spaced variants). Coverage: eForms award notices since 2023-10-25, above EU thresholds; ~57% of award notices carry a usable national identifier — an empty list is not proof of absence.

POST/v1/entreprise/%7Bsiren%7D/pi
base$0.0300

Intellectual property portfolio of a French company from official INPI open data: patents, trademarks and designs filed — counts plus recent items with number, title/label, status, date and classification. Designs: one line per filing. Covers French patents, trademark registrations and industrial designs in a single call, an R&D / brand-value signal not served to agents elsewhere, useful for due diligence on innovation assets. Patent inventor names (natural persons) are never returned.

POST/v1/entreprise/%7Bsiren%7D/risques-industriels
base$0.0100

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.

POST/v1/entreprise/%7Bsiren%7D/sante
base$0.1500

Company health check for a French company: a bilingual risk read-out — verdict, strengths, warning signs, activity trend and confidence level — from official data only (identity, BODACC alerts, filed financials, sanctions screening).
