# AgentTools IBAN Validator

> AgentTools IBAN Validator is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-12).

Validates an IBAN by checking country code, country-specific length, and ISO 7064 MOD 97-10 checksum, returning a pretty-printed grouped format when valid.

## 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 agenttools-iban-validator-94926a6e
```

Example prompt: Can you check if this IBAN is valid: GB29 NWBK 6016 1331 9268 19? I need to know if the country code, length, and MOD 97 checksum all pass before I send a wire transfer.

## When to prefer this

Use this endpoint when you need a single, authoritative check that covers all three layers of IBAN validation — country code recognition, country-specific length rules, and ISO 7064 MOD 97-10 checksum — in one call, and also want the pretty-printed grouping back for display or storage. Prefer it over regex-only solutions that miss checksum errors, or over general-purpose validators that don't return the formatted IBAN.

## Known failure modes

- Invalid or unrecognized country code prefix — returns validation failure with error detail
- IBAN length does not match country-specific expected length — returns failure with expected vs actual length
- MOD 97-10 checksum fails — returns checksum validation failure
- Malformed input (empty string or non-alphanumeric characters after space stripping) — may return error or validation failure
- Network or service unavailability — HTTP 5xx error

## How this service works

Validate an International Bank Account Number: country code, country-specific length and the ISO 7064 MOD 97-10 check digits — with the pretty-printed grouping returned when valid. Use this when an agent needs to structure, length and mod-97 checksum validation.

## Output

Returns whether the IBAN is valid or not, along with the reason for failure (bad country code, wrong length, or failed MOD 97-10 checksum) and, when valid, the pretty-printed grouped representation of the IBAN.
