## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability insee-sirene-french-company-lookup-4a8dbb3c -d '<json body>'

Example prompt: Can you check the official French Sirene register for the company 'Société Générale' and tell me if it's currently active, what its legal form is, its NAF code, and the registered head-office address?

## When to prefer this

Use this endpoint when you need authoritative, government-sourced data on a French company — specifically its legal status, form, activity codes, or registered address. Prefer this over generic business data providers when official INSEE Sirene accuracy is required, such as for compliance, KYB, or due diligence workflows. Note: does not return director or officer data.

## Known failure modes

- Company not found by SIREN — returns empty or not-found response
- Name search returns no candidates if name is too ambiguous or misspelled
- SIREN format invalid — request rejected with validation error
- API unavailable or upstream INSEE service down — returns 5xx error
- Search by name returns up to 5 candidates only; exact match not guaranteed

## How this service works

Official French company check from the INSEE Sirene register (French government open data). Look up by SIREN (exact) or search by name (up to 5 candidates). Returns official legal name, administrative status (active/ceased), legal form and NAF activity codes, company size category, creation/cessation dates, head-office address and SIRET, with a direct link to the official Annuaire des Entreprises. Companies only; no director or officer data.

## Output

Returns the official legal name, administrative status (active or ceased), legal form code, NAF activity code, company size category, creation and cessation dates, head-office address and SIRET number, and a direct link to the Annuaire des Entreprises page — all sourced from the INSEE Sirene register.
