## 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 tbs-company-siren-vat-lei-api-4405d43f
```

Example prompt: Can you look up the SIREN and EU VAT number for 'Société Générale' in France? I need the confidence score and ranked candidates from the official registers.

## When to prefer this

Choose this endpoint when you need to resolve a French company name or a European/global business entity into a verified SIREN, EU VAT, or LEI identifier for compliance, KYC/KYB, supplier onboarding, or France 2026 e-invoicing workflows. It is particularly valuable when you only have a brand name, trading name, or director surname — rather than the official identifier — because it cross-checks multiple authoritative registers (Sirene/RNE, GLEIF, EU VIES) in a single call and returns ranked candidates with confidence scores. Prefer this over manual register queries when building automated onboarding pipelines or compliance agents.

## Known failure modes

- Ambiguous company name with multiple close matches returns low-confidence candidates rather than a single best result
- Company not found in any of the three registers returns an empty candidates array
- Invalid or malformed VAT number input returns an error or zero matches
- Country scope mismatch (e.g. searching 'fr' for a non-French company) returns no results
- Very new or recently dissolved companies may not yet appear in official registers
- Rate limiting or payment failure returns a 402 or 429 error

## How this service works

Entity resolution for KYC/KYB, supplier and customer onboarding and France 2026 e-invoicing: use when you hold a company name, brand or director and need a certain identifier. Returns the French SIREN, EU VAT or global LEI with a confidence score and ranked candidates, cross-checked across official registers (recherche-entreprises Sirene/RNE, GLEIF LEI, EU VIES VAT). Input: name or vat, optional country, director, city.

## Output

Returns a best-match object containing the resolved identifier (SIREN, EU VAT, or LEI), the identifier type, the matched company name, and a confidence score, plus an array of ranked candidate matches, provenance details indicating which official registers were consulted, a unique request ID, and a generation timestamp.
