## 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 agentshelf-iban-ps-validator-26bd8a25 -d '<json body>'
```

Example prompt: Can you check whether PS92PALS000000000400123456702 is a valid Palestinian (PS) IBAN — specifically that it's 29 characters long and passes the mod-97 checksum?

## When to prefer this

Use this endpoint when you specifically need to validate a Palestinian Territory (PS) IBAN that must be exactly 29 characters and pass the mod-97 checksum. Prefer the free sandbox endpoint POST /v1/sandbox/check-iban-ps first during development to avoid the $0.002 USDC charge. Choose sibling endpoints for other country codes (LB, LI, MC, QA, etc.). Do not use this for general IBAN validation across multiple countries — each country has its own dedicated endpoint on this service.

## Known failure modes

- Input value missing or empty — rejected at schema validation
- Value exceeds 20,000 character limit — schema rejection
- Non-PS country code IBAN submitted — may return invalid result or country mismatch error
- Network timeout or service unavailability — HTTP 5xx
- Insufficient USDC balance for x402 payment — payment failure before processing

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid PS number of length 29. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/check-iban-ps first.

## Output

Returns a boolean or structured result indicating whether the submitted string is a valid PS (Palestinian Territory) IBAN: 29 characters long and passing the mod-97 checksum algorithm. No transformation is applied; the response reflects structural and mathematical validity only.
