## 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 turkish-iban-tr-validator-7517d877 -d '<json body>'
```

Example prompt: Can you check if this Turkish IBAN is valid: TR330006100519786457841326? I need to know if it passes the mod-97 checksum and is the right length for a TR account.

## When to prefer this

Use this endpoint when you specifically need to validate a Turkish (TR) IBAN and want a country-specific length check (26 chars) combined with mod-97 validation. Prefer this over the generic IBAN validator when you know the IBAN should be Turkish and want stricter country-specific enforcement. Always try the free sandbox endpoint (POST /v1/sandbox/check-iban-tr) before invoking this paid endpoint.

## Known failure modes

- Input string is not 26 characters — returns invalid
- IBAN does not start with 'TR' country code — returns invalid
- Mod-97 checksum fails — returns invalid
- Empty or missing input value — request error
- Input contains non-alphanumeric characters — may return invalid or error

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid TR number of length 26. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/check-iban-tr first.

## Output

A boolean or structured response indicating whether the submitted string is a valid Turkish (TR) IBAN — i.e., exactly 26 characters long, starts with 'TR', and passes the mod-97 checksum algorithm used for IBAN validation globally.
