## 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 iban-bic-check-2a1d021c -d '<json body>'
```

Example prompt: Can you validate the IBAN GB29NWBK60161331926819 and tell me the bank name, BIC, and whether it's a SEPA member?

## When to prefer this

Choose this endpoint when you need instant, offline IBAN validation with enriched bank metadata (BIC, bank name, SEPA status) at very low cost ($0.01/call). Ideal for payment pipelines, invoicing systems, and payout agents that need to pre-validate recipient bank details before executing transfers. Prefer this over live banking APIs when you need speed and reliability without round-trips to external banking infrastructure.

## Known failure modes

- Invalid IBAN format or characters (fails pattern match, 400 error)
- IBAN fails mod-97 checksum validation (returns invalid status)
- Country not recognized or BBAN checksum not defined for that country (partial validation)
- IBAN too short or too long (rejected by schema pattern)
- No bank registry entry found for given bank code (bank name/BIC may be absent)

## How this service works

Use when an agent needs IBAN validation before saving bank details, invoicing or a payout: structure, mod-97 and national BBAN checksum where defined, plus country, bank code, account code, bank name, BIC and SEPA membership. Offline registry, instant. Checks structure, not whether the account exists. $0.01 USDC on Base; charged only on 2xx, never for invalid input.

## Output

Returns a validation result indicating whether the IBAN passes structural, mod-97, and national BBAN checksum checks, along with parsed fields: country code, bank code, account code, bank name, BIC, and SEPA membership status. Sourced from an offline registry for instant response.
