# Share capital and ownership from public filings

The only route available in France to approach ownership, the beneficial-ownership register no longer being public. A proof guard frames the extraction: a clause is served only if its keyword actually appears in the document's text — a guard added after a non-existent pre-emption clause was produced for a real company.

## What the route returns

Catalogue description, exactly as agents read it:

**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.**

## Expected identifier

9-digit company number.

> ⚠️ A wrongly formatted identifier returns `400` and is **not billed** — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes.

## Price and billing

Price: **$0.35**. The authoritative amount is the one in the `402` quote returned by the route itself — not this text, which derives from the same grid but is still just a page.

An error response **cancels the payment**: a `400`, `404` or `503` is never billed. An upstream outage closes the route with a `503` rather than serving a degraded response.

## What this route does not do

This is **not** a beneficial-ownership register and does not replace one. Filed articles can be old: an unpublished share transfer does not appear. The document is immutable, extracted once then cached — read it as a dated exhibit, never as the current shareholding.

## 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](mailto:contact@sirenic.eu?subject=Euro%20credit%20packs) 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](https://api.sirenic.eu/openapi.json) and in [llms.txt](https://api.sirenic.eu/llms.txt).

**One call, end to end**
