# Unified profile of a European company

One route for eleven registers, and that is the whole point: your code need not know each one's quirks. The trade-off to accept is that a field a register does not publish stays absent — unification harmonises the shape, it does not invent missing data.

## What the route returns

Catalogue description, exactly as agents read it:

**European company profile by country code and national ID — official company registry data in one unified JSON schema: identity, legal form, status, creation date, head office, VAT, LEI, register link. Live: Norway, Estonia, Latvia, Belgium (KBO, NACEBEL + establishments), Czechia (ARES), Slovakia (RPO), Finland (PRH), Poland (KRS), Switzerland (Zefix, the Swiss company registry); Denmark and UK when enabled; elsewhere via GLEIF (LEI). European company data for KYB and due diligence.**

## Expected identifier

Two-letter ISO country code, then the NATIONAL identifier — whose format changes with every country. See the per-country pages.

> ⚠️ 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: **$0.01**. 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.

## Calling the route

```
# 1. Le devis, sans rien payer : la route répond 402 avec son montant
curl -i https://api.sirenic.eu/v1/eu/entreprise/{pays}/{id}

# 2. L'appel réglé — le client x402 paie le devis et rejoue la requête
npx x402-fetch https://api.sirenic.eu/v1/eu/entreprise/{pays}/{id}

# 3. Ou en MCP, dans Claude Code / Cursor / un agent
claude mcp add --transport http sirenic https://api.sirenic.eu/mcp
```

## Neighbouring routes

- `/v1/eu/recherche` — $0.003
- `/v1/eu/entreprise/{pays}/{id}/comptes` — $0.01

## 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**
