Sirenic

UK beneficial owners (UBO) — PSC, persons with significant control — of a UK company, live from Companies House, the official UK company registry: individual and corporate-entity PSCs with natures of control (ownership/voting bands), notification dates, plus official PSC statements. Ceased PSCs are excluded by default (inclure_cesses adds them with their ceased date). No open UBO register exists for France — this is UK-only depth. Month+year of birth only, no addresses. Paid via x402 ($0.02 in USDC or EURC).

One UK financial year — UK company financial statements decoded from the iXBRL accounts filed at Companies House: balance sheet (fixed and current assets, stocks, debtors, cash, creditors split by maturity, provisions, net assets, equity), average employees, and the profit and loss account when filed (turnover, operating, pre-tax and net result — most small companies file a balance sheet only), plus prior-year comparatives as published. Null = not published, never zero. Balance-sheet date comes from list_uk_company_accounts. Paid via x402 ($0.05 in USDC or EURC).

UK company insolvency record, live from Companies House, the official UK company registry: cases (compulsory or voluntary liquidation, administration, receivership...) with dates and insolvency practitioners (name and role only, no addresses). A company with no recorded case returns an explicit positive answer (aucune_procedure: true) — the register is authoritative. Paid via x402 ($0.02 in USDC or EURC).

UK company officers and directors, live from Companies House, the official UK company registry: directors and secretaries with role, appointment date, nationality, occupation, country of residence and month+year of birth only — never a correspondence address (GDPR minimisation). Includes active/resigned counts. Open Government Licence v3.0. Paid via x402 ($0.01 in USDC or EURC).

Belgian company annual accounts — list every published deposit of a Belgian company at the NBB CBSO (Central Balance Sheet Office, Authentic Data): deposit references with filing metadata as published. Unique on x402: no other service exposes Belgian filed accounts. Paid via x402 ($0.01 in USDC or EURC).

Danish company annual accounts — list the fiscal years of a Danish company whose XBRL annual report (Erhvervsstyrelsen, virk.dk publication index) has been decoded: closing dates, period, entity name, currency. Danish-taxonomy (fsa) filings only — IFRS/ESEF-only groups are not decoded, an empty answer does not mean no accounts exist. Paid via x402 ($0.01 in USDC or EURC).

Finnish company annual accounts — list the fiscal years a Finnish company has filed in XBRL with the PRH (Finnish Patent and Registration Office, CC BY 4.0). Only ~5% of Finnish limited companies file digitally — an empty answer does not mean no accounts exist. Empty filings are filtered out: every listed year carries figures. Paid via x402 ($0.01 in USDC or EURC).

List official documents filed by a French company at the INPI RNE registry: legal deeds (statutes, general-meeting minutes, mergers...) and filed annual accounts, with document IDs to download the PDFs. Paid via x402 ($0.02 in USDC or EURC).

List all establishments (SIRET) of a French company — branches and addresses with open/closed status, from the official French company registry. Paid via x402 ($0.003 in USDC or EURC).

Slovak company annual accounts — list the fiscal years of a Slovak company whose STRUCTURED financial statements have been decoded from the official Register účtovných závierok (RÚZ, registeruz.sk, Ministry of Finance, CC0): closing date, period, filing type (ordinary/extraordinary), form model, statutory vs consolidated scope, and the official document link. Filings served as PDF only — which includes every IFRS group — carry no structured data and are absent: an empty answer does not mean no accounts exist. Sole traders are not served (GDPR minimisation). Paid via x402 ($0.01 in USDC or EURC).

UK company annual accounts — list the financial years of a UK company whose iXBRL accounts (Companies House Accounts Data Product, Open Government Licence v3.0) have been decoded: balance-sheet dates, period, entity name, currency, accounting framework (micro-entity, FRS 102...) and accounts type. Electronically filed accounts only (~75% of UK filings) and depth accumulated since 2026-07 — an empty answer does not mean no accounts exist. Paid via x402 ($0.01 in USDC or EURC).

Use when the company you are about to invoice or pay is BELGIAN or POLISH and you must verify the supplier before payment (for France, use prepare_french_invoice_file). ONE call returns official registry identity, the VAT number checked against VIES, Peppol reachability for Belgium — whose structured B2B e-invoicing mandate has been in force since 1 January 2026 — and, uniquely in Poland, whether the IBAN is actually DECLARED by that taxpayer in the official White List (wykaz podatnikow VAT). The Polish check has FISCAL scope: paying more than 15,000 PLN into an undeclared account costs the buyer the deduction and creates joint liability for the supplier's VAT (art. 117ba Ordynacja podatkowa), so an undeclared account is a blocking reason. Returns a deterministic pret_a_facturer verdict with closed-list reasons, each tagged blocking or informational. The response is Ed25519-signed and carries provenance[] — one entry per block served, with the official register, its licence and its as_of date, the White List entry carrying the date actually sent to the ministry's API — so the payment decision is provable to an auditor offline. Paid via x402 ($0.03 in USDC or EURC).

Use when you need to PREPARE a compliant French e-invoice for a company (invoice header, VAT number, addressing) rather than decide whether paying it is safe — for the full verify-the-supplier-before-payment verdict, IBAN included, call prepare_french_invoice_file. The French e-invoicing mandate applies from 1 September 2026: receiving becomes obligatory for every VAT-liable company on that date, issuing is phased (large and mid-sized companies 1 September 2026, SMEs and micro-enterprises 1 September 2027; art. 91 of the 2024 Finance Act). Returns legal name & form, active/ceased status, computed intra-EU VAT number (+ VIES-check pointer), establishments (SIRET) with addresses, NAF code and indicative send/receive obligation dates from the INSEE size category. The response is Ed25519-signed and carries provenance[] — one entry per block served, with the official register, its licence and its as_of date — so the preparation is auditable offline. Preparation only — Sirenic is not an accredited platform (PDP), does not access the central directory and never issues, transmits or routes invoices, nor confirms PPF/PDP registration. Paid via x402 ($0.02 in USDC or EURC).

Use when you are about to invoice or pay a FRENCH company and must verify the supplier before payment: onboarding, first invoice, first payment, or bank details that just changed. The French e-invoicing mandate applies from 1 September 2026 (receiving obligatory for every VAT-liable company; issuing phased: large and mid-sized companies 1 September 2026, SMEs and micro-enterprises 1 September 2027), so every French counterparty has to be checked. ONE call returns the whole agent-side file: legal identity & obligation dates, the computed intra-EU VAT number verified LIVE against VIES, an IBAN check against official registries with the bank identified when `iban` is supplied, and a deterministic verdict pret_a_facturer (true/false) whose reasons come from a CLOSED list, each tagged blocking or informational and traced to its source. A VIES outage yields an honest informational reason, never a false invalid. Not a payee verification: the account holder's name is never checked. The response is Ed25519-signed and carries provenance[] — one entry per block served, with the official register, its licence and its as_of date — so the decision stays auditable offline months later. Paid via x402 ($0.03 in USDC or EURC).

French B2B prospecting and lead generation — build company lists over the full French registry (29.8M companies): filter by NAF activity code, departement/postal code, legal form, workforce, age, RGE certification, gender-equality index. Returns up to 100 active companies per page; each page is one x402 payment ($0.02 in USDC or EURC).

Renew a watchlist for 30 more days (possible until 7 days after expiry). The cibles parameter must repeat the exact watched targets — the quote is computed from it. Paid via x402 ($0.05 per target).

Use BEFORE any payment, contract or onboarding involving the name. AML sanctions screening of a person or company name against 6 official sanctions lists (UN consolidated, EU FSF, US OFAC SDN, UK Sanctions List, French asset-freeze register, Swiss SECO list). Returns fuzzy matches with a 0-100 confidence score — never a bare yes/no. Each list is reported with its entry count, its publication date and what that date means (official upstream publication vs. Sirenic ingestion — OFAC publishes none). Paid via x402 ($0.02 in USDC or EURC).

Search EU financial authorisations in ESMA Registers: ~14,000 MiFID-regulated entities across all EU/EEA countries (investment firms, UCITS/AIFM managers) by name or LEI — authorisation status, home and host member states, competent authority, dates. Use to verify that a financial firm is actually regulated somewhere in the EU. Data freely available at the source (ESMA). Paid via x402 ($0.01 in USDC or EURC).

European company search — company lookup by name across official European company registers in one unified schema (Norway, Estonia, Latvia, Spain — BORME base, hoja key — local; Czechia, Slovakia, Finland, Poland, Switzerland live; Denmark/UK when enabled; worldwide GLEIF/LEI coverage). Each match carries a score_confiance (0-1 match confidence). Spanish matches return the hoja registral to use with get_spanish_company_acts. Paid via x402 ($0.003 in USDC or EURC).

Use FIRST whenever a French company is mentioned by NAME without an identifier. French company search and company lookup by name or SIREN in the official French company registry (INSEE Sirene / INPI RNE data). Returns the top 10 matches, each with a score_confiance (0-1 match confidence, helps pick among homonyms). Paid via x402 ($0.001 in USDC or EURC).

Reverse search for company directors and officers in France — a people search by surname: list the French companies where a person of a given surname holds (or held) an office, with the company SIREN, name and the person's role — for due diligence and network mapping. Person data limited to surname, first names, role and birth year. Homonyms are not disambiguated; common names are capped. Paid via x402 ($0.02 in USDC or EURC).

Stop a watchlist and purge its data immediately (free).

VAT number check against VIES — use when you only need the tax half of verifying a supplier before payment: confirm that a counterparty's intra-community VAT number really exists before invoicing it, applying the reverse charge or paying it. It is a required check under the French e-invoicing mandate of 1 September 2026 and under the Belgian B2B mandate in force since 1 January 2026. Validates any EU intra-community VAT number against the official VIES service (all member states) and returns valid / invalid / unavailable, the registered name and address when the member state publishes them, and the VIES consultation identifier as proof. A member-state outage is reported as unavailable, never as a false invalid. The response is Ed25519-signed and carries provenance[]: the VIES entry with the date the number was really consulted, never a fabricated one. Paid via x402 ($0.003 in USDC or EURC).

IBAN verification and bank validation for SEPA — use when you are about to pay a NEW or CHANGED IBAN, or when onboarding a supplier's bank details, and want the cheapest check of the supplier before payment. Validates the IBAN (ISO 13616 structure + mod-97), identifies the bank from FREE official registers (France: name+LEI+SIREN via ACPR/REGAFI; Belgium, Austria, Netherlands: name+BIC; Germany when the Bundesbank file is loaded, incl. LEI where available; French banks get their BIC via the GLEIF/SWIFT BIC-to-LEI mapping). Explicitly NOT a payee verification — the account holder's name is never checked and the account's existence is not tested (verification_titulaire: non_disponible): a well-formed IBAN at an identified bank is no proof that the account belongs to your supplier. The response is Ed25519-signed and carries provenance[] — one entry per block served, naming the official register actually consulted, its licence and its as_of date. For the full invoicing verdict on a French counterparty, call prepare_french_invoice_file instead. Paid via x402 ($0.005 in USDC or EURC).
