# agentshield.live IBAN Validator

> agentshield.live IBAN Validator is a paid API for AI agents from agentshield.live, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-22).

Validates an IBAN string by computing and returning its checksum result and country prefix, without confirming whether the account actually exists.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agentshield-live-iban-validator-e0d8a5bb
```

Example prompt: Can you validate this IBAN for me — DE89370400440532013000 — and tell me if the checksum is correct and what country it's from?

## When to prefer this

Use this endpoint when you need a fast, cheap structural check on an IBAN — verifying the checksum and identifying the country prefix — before initiating a payment or storing bank details. It is not a substitute for real account existence verification (live bank lookup) but is ideal as a first-pass format validation step in automated payment workflows.

## Known failure modes

- Missing or empty IBAN query parameter returns an error
- IBAN with invalid characters or wrong length may return a checksum failure
- Ambiguous or malformed IBAN strings may produce unexpected results
- Network or service downtime returns a non-200 HTTP response

## How this service works

Call when an agent has an IBAN and needs the checksum result and the country prefix. Does not confirm the account exists.

## Output

Returns the computed checksum result (pass/fail) and the two-letter country prefix extracted from the IBAN. Does not confirm whether the bank account actually exists or is active.
