Sirenic or the INPI register directly

The INPI is our supplier, not our competitor — and its data is free. So the question is not “who is better” but “at what point does paying an intermediary cost less than doing it yourself”. That is a calculation, and it does not always favour us.

What INPI (Registre national des entreprises) does better than us

Let us start there, because it is what decides half the cases — and because a comparison where the competitor never wins anything does not deserve to be read.

It is the source, and it is free. A team with time to ingest, deduplicate and maintain needs nobody else — that is precisely what Sirenic does internally for part of its own foundation.
The 1993-onwards deed history and the documentary depth of the register exceed what we expose.
No intermediary: no risk that a third party mis-read a field.

When to ingest the INPI yourself

You have engineering time and a lasting need: the source is free, company data refreshes daily, and in the long run nothing beats zero data cost.
You want the full documentary depth, including deeds and articles since 1993 — more than we expose.
You want no intermediary between the source and your decisions, so as not to depend on a third party's interpretation.

INPI (Registre national des entreprises): what we found

Surveyed on 2026-08-19, source: https://www.inpi.fr/ressources/formalites-dentreprises/acces-lapi-formalite-rne. Every line is verifiable by you, at the same address.

Business-register data is distributed free of charge; access is managed from an account, under “Mes accès API / SFTP”.
Stated refresh rates: daily for companies, weekly for trademarks and patents, fortnightly for designs.
Content: new-registration feed, accounting data (assets/liabilities, income statements, fixed assets, depreciation and provisions), and “deeds and articles of legal and natural persons since 1993”.
Formats: JSON or XML notices, associated documents as PDF.

What Sirenic does differently

Pay per call, no account, no key. A 402 call, a settlement in USDC or EURC, the response. No sign-up, no contract, no IP address to declare, no expiring credits. 79 routes are reachable that way.
An upstream outage closes the route. We answer 503 and cancel the payment rather than serve a degraded response. A registry snapshot that is too old also closes the route that reads it, instead of selling dead data.
Ed25519-signed responses. You can prove months later what was served to you, and when.
Per-block provenance. Each block of a file declares its official registry and as-of date, rather than a blanket “official sources” claim.
What ingesting really costs. We know because we do it: the source publishes heterogeneous formats, part of the feeds fails silently, and some datasets truncate amounts beyond a 32-bit integer bound — a trap that makes almost every line item of the largest companies wrong if you do not know it. The real cost is not downloading, it is maintaining.
Several cross-referenced sources, not one. Identity registry, legal notices, financial ratios, sanctions, authorisations from three authorities, public contracts, regulated industrial sites, lobbying, thirteen European registers — each with its own publication calendar and its own outages.
Freshness guards that stop the sale. When one of our copies exceeds its age threshold, the route returns 503 instead of serving a dead snapshot. A home-grown ingestion has that safeguard only if someone writes it.
A verdict, not raw rows. A score with its scorecard, an invoice-coherence verdict, screening with a per-hit score: that is interpretation work on top of the source, not the source.

The foundation, in measured figures

Measured in our database on 2026-08-19: 29,922,486 company numbers and 43,896,818 establishments, 6,542,232 financial years across 1,586,046 companies, 3,402,583 detailed tax-form line items, 9,196,396 registry filings, 765,960 public contracts of which 173,633 expire within 18 months, 130,165 names across 6 official sanctions lists, 47,731 authorisations from 9 authorities, 138,020 regulated industrial sites and 2,934 sectors with statistics.

These are a dated snapshot from 2026-08-19, not a live counter. We republish them at each measurement rather than round them up.

How this comparison is built

Every fact carries its survey date and its source address, so that you can contradict it. Nothing is extrapolated: what we could not survey is marked as not surveyed rather than guessed. And every page names what the compared service does better than us — a comparison without that section is not a comparison.

If you spot an error or a fact that has become false, write to contact@sirenic.eu: we will correct the page and its survey date.

How you pay

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.

Routes used and pricing

Route	Price	What it returns
`/v1/entreprise/{siren}/finances` (free sample)	$0.01	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.
`/v1/entreprise/{siren}/documents` (free sample)	$0.02	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.
`/v1/entreprise/{siren}/capital` (free sample)	$0.35	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.
`/v1/score/defaillance/{siren}` (free sample)	$0.10	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.

The default-risk score is a decision-support indicator. It is neither a solvency opinion nor a credit rating in the regulatory sense, and it guarantees no payment.

The ownership data served for France is not a beneficial-ownership register and does not replace one: the French register has not been publicly accessible since the 2022 ruling of the Court of Justice of the European Union. What is served comes from publicly filed deeds.

Frequently asked questions

Does your data come from the INPI?

In part, yes, and we do not hide it: every response block declares its source registry and as-of date. The rest comes from other official sources — identity registry, legal notices, regulators, public-procurement data, European registers.

At what volume is doing it yourself cheaper?

It depends on your engineering cost, not ours. An honest rule of thumb: if you need a single source and recurring bulk processing, ingest it. If you need several cross-referenced sources, a verdict, or occasional use, the intermediary is cheaper than the maintenance.
