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. Sources : Annuaire des Entreprises (DINUM), BODACC (DILA), ADEME — Licence Ouverte Etalab 2.0. Informations issues de sources publiques, fournies à titre indicatif. Ne constitue pas un conseil.

Output

Returns a JSON object with: a scored verdict (favorable/vigilance/unfavorable) with a confidence level and plain-text summary; an array of sourced signal codes (e.g. AUCUNE_PROCEDURE_COLLECTIVE, ENTREPRISE_ETABLIE, NUMERO_TVA_VALIDE) each with level (positif/info/alerte), source, message, and optional date/proof; full company data including legal state, head office address, NAF activity code, headcount band, category (SME/GE), VAT number validity, quality labels (RGE, Qualiopi, ESS, Bio, Société à Mission), open establishments count, and data freshness timestamp. All data is sourced from French official open data under Etalab 2.0 licence.

Example use cases

Supplier onboarding risk check

“Before we onboard this French supplier, can you verify SIREN 448038455 and tell me if they're active, whether there are any bankruptcy or liquidation proceedings against them, and what the overall risk verdict is?”

RGE-certified contractor verification

“I need to confirm that this French renovation contractor (SIREN 384071937) actually holds a valid RGE certification — can you check their status and labels?”

Automated procurement compliance gate

“We're automating our French vendor approval process — can you check SIREN 342493572 and flag it if the verdict comes back as vigilance or unfavorable due to insolvency or closed status?”

Technical details

Endpoint

GEThttps://api-production-24833.up.railway.app/v1/verify?utm_source=zero.xyz

When to prefer

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.

Side effects

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
