## 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 iranian-bank-card-pan-luhn-validator-686fc81f
```

Example prompt: Can you check if the Iranian bank card number 6037991234567890 is valid and tell me which bank issued it?

## When to prefer this

Use this endpoint when you need to validate Iranian bank card (PAN) numbers specifically — it applies Luhn algorithm validation and maps Iranian BIN prefixes to issuer bank names in Persian, which generic international card validators do not support. Prefer it over a generic Luhn checker when you also need to identify the Iranian bank behind the card number.

## Known failure modes

- Missing or empty 'value' query parameter returns a 400-level error
- Non-16-digit input may return valid:false or an error
- Unrecognized BIN prefix returns valid:true but issuer may be null or unknown
- Network timeout on the Cloudflare worker returns 5xx
- Payment not included or insufficient USDC causes x402 payment-required response

## How this service works

Persian (Farsi) and Iranian utility API for AI agents. Text normalization, transliteration, Jalali (Solar Hijri) calendar conversion, Persian digits and number-to-words, Iranian national ID / Sheba (IBAN) / mobile / landline / postal code / bank card (Luhn PAN) / company ID / economic code validators, Iranian provinces and cities, official Jalali holidays, Rial-Toman conversion. Also a FIXED-PRICE deliverable SKU: Persian/Arabic data cleanup at $0.90, $9 or $25 flat per file (not per call) - upload a CSV, TSV or text file and get it back normalized, with an optional Latin transliteration column. Pay per request in USDC on Base via x402 - no signup, no API key, no KYC.

## Output

A JSON object with a 'valid' boolean indicating whether the card passes the Luhn check, and an 'issuer' string with the name of the issuing Iranian bank in Persian (e.g. بانک ملی). Returns valid:false with no issuer if the card number is invalid.
