## 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 eu-business-kyb-verification-vies-gleif-iban-646e1b78
```

Example prompt: Can you run a full KYB check on our new Lithuanian supplier — their VAT number is LT123456789, country code LT — and tell me if they pass, need review, or fail, along with any flags?

## When to prefer this

Choose this endpoint when you need a single, consolidated KYB verdict for an EU business combining multiple official data sources in one call — especially when you have partial identifiers (just a VAT, just an LEI, just an IBAN, or just a name) and want cross-validated confidence rather than checking each registry separately. Prefer this over individual VAT, LEI, or IBAN endpoints when you need a unified pass/review/fail decision for onboarding or compliance workflows.

## Known failure modes

- Invalid or malformed VAT number returns validation error
- LEI not found in GLEIF registry returns unknown status
- IBAN checksum failure flagged as invalid
- Country code not an EU member state causes VIES lookup to fail
- Insufficient identifiers provided (need at least one of: country+vat, lei, name, or iban)
- Upstream VIES or GLEIF service downtime causes degraded or unavailable verdict
- Company name too generic to resolve uniquely returns low-confidence result

## How this service works

Verify / due-diligence an EU business in ONE call (KYB). Give any of {country+vat, lei, name, iban}; fuses official EU VAT (VIES) validation, GLEIF LEI status, public entity resolution and IBAN checksum into one scored verdict (pass/review/fail) with confidence and flags. Use to onboard, validate a counterparty, or KYB-check a supplier/customer before transacting. Returns a single structured decision object.

## Output

A single structured decision object containing a scored verdict (pass, review, or fail), a confidence score, and an array of flags explaining any issues — aggregating results from VIES VAT validation, GLEIF LEI status, public entity resolution, and IBAN checksum where applicable.
