## 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 moneytools-iban-validator-17b9ab95 -d '<json body>'
```

Example prompt: Can you check if this IBAN is valid: GB82 WEST 1234 5698 7654 32? I want to know if the check digits pass and what the BBAN is.

## When to prefer this

Use this endpoint when you need a lightweight, stateless IBAN validation that checks both structural correctness (country length rules) and mod-97 check digits without storing any data. Ideal for fintech workflows, payment onboarding, or any agent that needs to verify a user-supplied IBAN before initiating a transfer. It is priced per-call at $0.001 USDC via x402, making it cost-effective for low-to-medium volume; use the free tier (10/day) for development or testing.

## Known failure modes

- Invalid IBAN format or checksum — validation fails with error details but no charge
- Unrecognized country code — IBAN country prefix not supported
- Malformed input string — non-IBAN characters rejected
- Rate limit exceeded on free tier (10/day) without payment credentials — HTTP 429 or 402
- x402 payment failure — call not processed if payment cannot be completed

## How this service works

IBAN validator: Check an IBAN's country length and mod-97 check digits, return BBAN and print format. Not stored. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.

## Output

Returns a validation result indicating whether the IBAN passes the mod-97 check and country-specific length rules, along with the extracted BBAN (Basic Bank Account Number) and the print-formatted version of the IBAN (grouped with spaces). On failure, the endpoint is not charged.
