## 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 verif-entreprise-fr-single-siren-verification-ef61a1d6
```

Example prompt: Can you run a full KYB check on the French company with SIREN 552032534 and tell me if it's safe to work with — I want to know its legal status, any insolvency proceedings, and the overall verdict?

## When to prefer this

Choose this endpoint when you need a single, authoritative, real-time KYB verdict on a French company by SIREN from official French government open data sources, including insolvency status from BODACC, VAT validity from VIES, and quality labels (RGE, Qualiopi). Prefer it over generic company data APIs when regulatory compliance, supplier risk scoring, or contractual due diligence requires sourced, explainable signal codes with a clear favorable/vigilance/unfavorable verdict. Use the batch sibling endpoint when verifying more than one company at a time.

## Known failure modes

- Invalid or non-Luhn-valid SIREN returns a 400 validation error
- SIREN not found in the national directory returns a 404 or unfavorable verdict with signal code
- Upstream official data sources (BODACC, DINUM, VIES) temporarily unavailable may lower confidence to 'partielle' and omit some signals
- Mismatched optional 'nom' parameter returns aucune match signal but does not block the call
- Rate limiting or payment failure returns a 402 error requiring x402 payment

## How this service works

Agrège l'Annuaire des Entreprises, le BODACC et la liste RGE de l'ADEME, et renvoie un verdict expliqué par des signaux sourcés (codes stables, voir docs/signaux.md). Paiement à l'appel en USDC via x402, sans compte ni clé API.
