The French e-invoicing mandate makes reception mandatory for every VAT-liable company on 1 September 2026, with issuance phased in (large companies and mid-caps in 2026, SMEs in 2027). What actually blocks projects is almost never the software: it is a supplier master file with wrong company numbers, stale legal names and VAT numbers nobody ever checked.

/v1/kyb/batch accepts 2 to 100 company numbers in a single call and returns a full file per company: identity, officers, court-bulletin alerts, filed accounts, sanctions screening, computed VAT number and a completeness score. The amount is quoted from the number of company numbers passed, and the batch unit price is lower than the single-call price.
A company number matching no publicly listed company comes back as trouve=false and counts as one lookup: the response does not hide the rows it could not resolve, which is exactly what you want from a clean-up tool.
Every block in the file states which official registry it comes from and as of which date. On a compliance project, that is the difference between “our data comes from a vendor” and “this row comes from that registry, on that date” — only the second holds up in front of an auditor or an inspection.
For one supplier, /v1/entreprise/{siren}/facturation-prep returns: legal name and form, status, computed intra-EU VAT number (with a pointer to VIES validation), establishments and their identifiers with addresses, industry code, and the indicative obligation dates that apply.
Neither the central directory, nor issuance, nor routing, nor the choice of an accredited platform. The obligation dates served are indicative: they help you sort a master file, they do not replace an analysis of your own tax position.
Sirenic is not an accredited French e-invoicing platform (PDP), never accesses the central directory, and neither issues, transmits nor routes any invoice. These routes prepare and verify data; carrying the invoice remains your platform's job.
/v1/recherche — the cheapest route in the catalogue, and it returns a confidence score that disambiguates namesakes./v1/kyb/batch to get identity, alerts and screening at once.Every route is paid per call, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.
Would you rather have a euro invoice and prepaid credits? That is in preparation, and we will not announce a date until it is open. Write to contact@sirenic.eu and we will let you know when it opens.
Paid responses are Ed25519-signed: you can later prove what was served to you, and when. The whole catalogue is free to read in the OpenAPI document and in llms.txt.

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. |
/v1/recherche (free sample) | $0.001 | 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. |
/v1/facturation/dossier (free sample) | $0.03 | Invoice verification and supplier verification — verify supplier before payment in France, the invoicing pack of the e-invoicing mandate France September 2026 (all VAT-liable companies must receive): legal identity, obligation dates, intra-EU VAT number checked LIVE against VIES, IBAN form + key check, bank identified, deterministic pret_a_facturer verdict, closed-list reasons.

Ten calls of 100 company numbers, billed at the batch unit price shown in the table below, times 1,000. The quote is computed and frozen before settlement: you see the exact amount before paying, never after.
No, they are indicative and meant for sorting. The real timetable depends on company size and circumstances; the response says so, and your tax adviser decides.
No account to create, no key to request: the first step is free and shows you exactly what you would be buying.
