## How to call it through Zero

```sh
zero fetch --capability sirenic-french-e-invoice-preparation-a5731bc4
```

Example prompt: I need to prepare a compliant French e-invoice for the company with SIREN 552032534 — can you pull their legal name, VAT number, SIRET establishments, NAF code, and their 2026 mandate obligation dates?

## When to prefer this

Use this endpoint when you need to assemble all the legally required fields to prepare a French B2B e-invoice compliant with the September 2026 French mandate, and you only have a SIREN. It is the right choice when you need VAT number, SIRET, legal form, NAF code, and obligation timeline in a single call. Do not use it if you need to actually submit or route invoices (that requires an accredited PDP platform), access the central Chorus Pro directory, or verify real-time VAT validity independently.

## Known failure modes

- Invalid or non-existent SIREN (9 digits required) returns a 404 or validation error
- Company dissolved or struck off may return limited or flagged data
- VIES lookup temporarily unavailable may result in partial VAT data
- Rate limiting or payment failure returns 402 Payment Required
- Network timeout on INSEE upstream returns 503

## How this service works

Supplier onboarding: PREPARE a compliant French e-invoice under the e-invoicing mandate France September 2026 (reception obligatory for every VAT-liable company; issuance phased GE/ETI 2026, SME 2027): legal name & form, status, computed intra-EU VAT number (with VIES pointer), establishments (SIRET) with addresses, NAF code, indicative obligation dates. Preparation only - Sirenic is not an accredited platform (PDP), never accesses the central directory and never issues or routes invoices.

## Output

A structured JSON response containing the company's legal name and form, current status, computed intra-EU VAT number with VIES reference, list of SIRET establishments with full addresses, NAF activity code, INSEE size category, and indicative dates for when the French e-invoicing mandate applies to this entity. This is preparation data only — no invoice is issued or routed.
