## 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 invoket-iban-resolve-6da04faa
```

Example prompt: Can you resolve the IBAN DE89370400440532013000 and tell me the bank name, BIC, and whether it's reachable for payments?

## When to prefer this

Use this endpoint when you need to resolve an IBAN to its underlying bank details (BIC, bank name, reachability) without setting up an account or API key, especially in autonomous agent workflows that support x402 stablecoin micropayments. Prefer this over bank data APIs requiring registration when you need lightweight, pay-per-call access to national bank registry data.

## Known failure modes

- Invalid or malformed IBAN returns validation failure
- IBAN from unsupported country may return partial coverage or no bank data
- Missing required query parameter returns 400 bad request
- Payment not settled (x402 protocol failure) returns 402 Payment Required
- Rate limiting or network issues may return 5xx errors

## How this service works

The checks your agent runs before it acts: verify a bank account, a phone number, a law in force, the weather or a vehicle — computed from official sources, with provenance in every response. You only pay for answers.

## Output

Returns a JSON object containing the validated IBAN, whether it is valid and reachable, the associated bank name and BIC, country code, bank code, coverage level, and provenance metadata including the data source and freshness timestamp.
