## 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 financial-identifiers-batch-validator-089798ab -d '<json body>'
```

Example prompt: Can you validate these three financial identifiers for me in one go — GB29NWBK60161331926819, DEUTDEDB, and 021000021 — and tell me which ones are valid?

## When to prefer this

Use this endpoint when you need to validate multiple financial identifiers (IBANs, BICs, account numbers, routing numbers) in a single request rather than one at a time. Prefer this over single-item validation endpoints when processing a list of identifiers as part of payment pipeline validation, data quality checks, or onboarding flows.

## Known failure modes

- Empty or malformed items array returns error
- Unsupported identifier format may return valid:false without explanation
- Rate limiting or payment failure returns non-200 status
- Large batch sizes may exceed limits
- Network timeout for very large arrays

## How this service works

Validate up to 500 mixed financial identifiers in one call. Each item may specify type iban, vat, card or auto.

## Output

A JSON object containing ok status, a count of processed items, and a results array where each entry has a 'valid' boolean corresponding to each submitted identifier in order.
