# Verif Entreprise FR — French Company Name Search (SIREN Lookup)

> Verif Entreprise FR — French Company Name Search (SIREN Lookup) is a paid API for AI agents from api-production-24833.up.railway.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-11).

## 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-french-company-name-search-siren-lookup-6b0f6d9d
```

Example prompt: Can you find the SIREN and registration details for a French company called 'Boulangeries Paul' located in Lyon (postcode 69003)?

## When to prefer this

Use this endpoint as the first step when you have a French company name but not its SIREN, and need to identify the correct legal entity before proceeding to full KYB verification. It is ideal for supplier onboarding, contract pre-screening, or any workflow where you must resolve a company name to an official French registry identifier. Prefer this over the single-SIREN /v1/verify endpoint when you don't yet have the SIREN. Use the postcode or commune filter to disambiguate common company names.

## Known failure modes

- Query string too short (under 3 characters) — validation error
- No matches found for the given name/postcode combination — empty results array
- INSEE commune code format mismatch (wrong pattern) — validation error
- Postcode not matching 5-digit format — validation error
- Upstream DINUM API unavailable — source status not 'ok', degraded results
- Rate limiting or payment failure via x402 — HTTP 402 response
