## 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 iban-validator-6a400e41
```

Example prompt: Can you check whether GB82 WEST 1234 5698 7654 32 is a valid IBAN and tell me the country and formatted version?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call IBAN validation without setting up a dedicated banking SDK or subscription service. Ideal for AI agents that sporadically validate IBANs as part of a payment or onboarding workflow, since the $0.001 USDC per-call pricing means no wasted spend on idle subscriptions. Prefer this over free regex-only checks when you also need parsed output like BBAN, country, and formatted string.

## Known failure modes

- Missing `iban` query parameter returns an error response
- Invalid or malformed IBAN returns valid=false with a descriptive errors array
- Unsupported or unknown country prefix may return valid=false
- Payment failure (x402) if USDC balance is insufficient or wallet not configured

## How this service works

Email checks, DNS and email-authentication audits, website contact extraction, SEO audits, URL to Markdown and Swedish validators, paid per call in USDC with x402.

## Output

A JSON object with: `valid` (boolean), `errors` (array of validation error strings, empty if valid), `country` (ISO 2-letter country code), `formatted` (space-grouped human-readable IBAN), `normalized` (compact IBAN without spaces), `bban` (Basic Bank Account Number portion), and `check_digits` (2-digit checksum string).
