## 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 signaldesk-ai-iban-validator-868cd526 -d '<json body>'
```

Example prompt: Can you check whether this IBAN is valid: GB29 NWBK 6016 1331 9268 19 — tell me if the checksum and length are correct and which country it belongs to?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.001 USDC) programmatic check of any IBAN's structural validity — checksum, length, and country support — prior to initiating a payment or onboarding a bank account. Prefer this over manual regex checks or expensive banking API integrations when you only need format/checksum validation and country identification, not full account existence confirmation.

## Known failure modes

- Malformed or non-IBAN string returns failed validation flags
- IBAN from unsupported country returns supported_country: false
- Network or worker timeout returns no response
- Payment not included or insufficient USDC results in HTTP 402 before validation runs
- IBAN longer than 64 characters rejected at input schema level

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing: the two-letter country code extracted from the IBAN, a boolean indicating whether the account has been positively verified, a boolean for whether the country is supported, and a boolean confirming whether the checksum and length are valid per IBAN standards.
