## 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`):

```

Example prompt: Before I send an invoice, can you verify that French company with SIREN 552 032 534 is still active and give me their official legal name, legal form, and registered head-office address from the INSEE Sirene register?

## When to prefer this

Use this endpoint when you need authoritative, official French company data directly from the INSEE Sirene register (30M+ legal units) before invoicing, paying, or onboarding a French entity. Prefer it over general business search tools when you have a SIREN or SIRET number and need structured, machine-readable legal metadata without requiring an account or API key.

## Known failure modes

- SIREN/SIRET not found in the register — company never existed or number is malformed
- Company exists but record is stale if queried between monthly snapshots
- Invalid SIREN/SIRET format returns a 4xx error
- Payment not attached or insufficient — x402 payment required error
- Rate limiting or network timeout on high-volume calls

## How this service works

Verify a French company before you invoice, pay or onboard it: legal name, active/ceased status, legal form, NAF activity, workforce band, creation date and head-office address from the official INSEE Sirene register (30M+ legal units, monthly snapshot). Lookup by SIREN or SIRET. No account, no key, pay per call.

## Output

Returns the company's official legal name, active or ceased status, legal form (e.g. SAS, SARL), NAF/APE activity code, workforce band, creation date, and registered head-office address as recorded in the INSEE Sirene register.
