# AgentTools IBAN Validator

> AgentTools IBAN Validator is a paid API for AI agents from agenttools-hub.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Validates an IBAN by checking country code, country-specific length, and ISO 7064 MOD 97-10 check digits, returning 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-3d8140ef
```

Example prompt: Can you check if this IBAN is valid: GB82WEST12345698765432? I want to make sure the country code, length, and checksum are all correct before I send a wire transfer.

## When to prefer this

Use this endpoint when you need to validate a single IBAN with full structural, length, and cryptographic checksum verification before initiating a bank transfer, onboarding a vendor, or accepting user-provided bank account details. Prefer this over basic regex checks because it performs MOD 97-10 checksum verification and country-specific length rules, not just format matching.

## Known failure modes

- Invalid country code — unrecognized two-letter prefix
- Wrong length for country — IBAN does not match expected character count for the given country
- MOD 97 checksum failure — check digits do not pass ISO 7064 validation
- Missing or empty IBAN query parameter — returns error requiring the iban field
- Malformed input that cannot be parsed as an IBAN

## 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 a validation result indicating whether the IBAN is valid, with details on the country code, expected vs actual length, and MOD 97-10 checksum outcome. When valid, also returns the pretty-printed grouped IBAN string. When invalid, returns the specific reason for failure (bad country code, wrong length, or failed checksum).
