## 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 hcrb-in-vendor-onboarding-pack-b602bc9e -d '<json body>'
```

Example prompt: Before we add this vendor to our system, run a structural check on their identifiers: IBAN GB29NWBK60161331926819, LEI 2138005O9XJIJN4JPN90, Belgian VAT BE0472429986, and UK company number 01234567.

## When to prefer this

Use this endpoint when you need fast, offline, deterministic structural validation of European and UK business identifiers (IBAN, LEI, Belgian VAT, UK company number) in a single call — ideal for vendor onboarding pre-screening workflows. Do not use when you need live registry lookups, beneficial ownership data, fraud scoring, or validation of non-BE/UK VAT numbers.

## Known failure modes

- Malformed IBAN fails checksum validation — error flag returned for that field
- LEI format does not match 20-character alphanumeric structure — flagged as invalid
- Belgian VAT number fails mod-97 check — returned as structurally invalid
- UK company number does not match expected format — flagged accordingly
- All fields are optional; submitting an empty payload returns no useful validation output
- No network or registry errors since checks are fully offline/deterministic

## How this service works

Check supplied IBAN, LEI, Belgian VAT and UK company-number fields in one result. Structural checks only; no ownership, registry or fraud clearance.

## Output

Returns a structured result with field-level pass/fail indicators for each submitted identifier (IBAN, LEI, Belgian VAT, UK company number), reflecting purely structural/algorithmic correctness — no live registry lookups, ownership data, or fraud signals.
