## How to call it through Zero

```sh
zero fetch --capability strale-iban-to-bank-lookup-f5c2aea6
```

Example prompt: Can you look up the bank details for the IBAN DE89370400440532013000 — I need to know which bank it belongs to and get the BIC if possible?

## When to prefer this

Choose this endpoint when you need a trusted, auditable IBAN-to-bank resolution with cryptographic proof of the lookup — particularly in compliance, fintech, or agent-driven payment workflows where an audit trail matters. Useful when operating across the 27+ countries Strale covers and when you need structured JSON output that can be programmatically validated.

## Known failure modes

- Invalid IBAN format returns validation error
- IBAN for an unsupported country or bank may return limited data
- Malformed IBAN checksum triggers rejection
- Rate limiting or payment failure (x402) prevents execution
- Unknown or defunct bank may return incomplete records

## How this service works

Extract bank name and branch information from an IBAN. Returns bank name, BIC/SWIFT code, branch, and country. Pure algorithmic — uses bank code lookup tables.

## Output

Returns structured bank information for the given IBAN including bank name, BIC/SWIFT code, country, branch details, and IBAN validity status, along with a cryptographic audit record for trust verification.
