## 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 veriffr-french-company-vat-lookup-api-bd703d6e
```

Example prompt: Can you look up TotalEnergies Marketing France and give me their SIRET, VAT number, and registered address? I want to confirm they're an active company before we sign a supplier contract.

## When to prefer this

Choose this endpoint when you need authoritative French company data (SIRET, SIREN, VAT, address) without needing an API key or monthly subscription — ideal for pay-per-call agent workflows doing one-off supplier verification, invoice validation, or CRM enrichment. Prefer it over full KYB platforms when you only need registry-level facts about French entities rather than full identity verification with documents.

## Known failure modes

- No match found for the given company name or identifier — returns empty results or 404
- Ambiguous company name returns multiple results up to the limit; caller must refine query
- Invalid or malformed SIRET (not 14 digits) causes a validation error
- Rate limiting or payment failure on the x402 micropayment layer results in 402 response
- Company exists but has no VAT number (e.g. micro-enterprises below VAT threshold) — VAT field may be null

## How this service works

Verify French companies, EU VAT numbers, and addresses from one API. Pay per call with USDC on Base via x402. No account, no API key.

## Output

Returns a JSON object with the company's official name, SIRET (14-digit), SIREN (9-digit), EU VAT number, full registered address, city, NAF activity code, active/inactive status, and employee band (e.g. '1000-1999 employees').
