## 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 saudi-arabia-iban-validator-sa-length-24-ac4a6d2d -d '<json body>'
```

Example prompt: Can you check if this Saudi Arabia IBAN is valid: SA4420000001234567891234?

## When to prefer this

Use this endpoint when you specifically need to validate a Saudi Arabia IBAN (SA prefix, 24-character format) and require a mod-97 checksum verification. Prefer the free sandbox endpoint (/v1/sandbox/check-iban-sa) for testing. Choose this paid endpoint for production validation where a confirmed result is needed before executing a financial transaction to a Saudi bank account.

## Known failure modes

- Input string is not 24 characters — validation returns invalid
- IBAN does not start with 'SA' — fails country code check
- Mod-97 checksum does not pass — returns invalid
- Empty or missing value field — request rejected
- Non-string or malformed input — error response

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid SA number of length 24. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/check-iban-sa first.

## Output

Returns a boolean or structured result indicating whether the input string is a valid Saudi Arabia IBAN: correctly prefixed with 'SA', exactly 24 characters in length, and passing the mod-97 checksum algorithm.
