## 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 irantools-iranian-holiday-check-8b26e328 -d '<json body>'
```

Example prompt: Is the 1st of Farvardin 1403 an official public holiday in Iran according to the Iranian Solar Hijri calendar?

## When to prefer this

Use this endpoint when you need to determine whether a specific Jalali (Solar Hijri) calendar date is an official Iranian public holiday — especially in workflows involving Iranian business scheduling, payroll, compliance, or calendar automation. Prefer this over manual lookup or general-purpose LLM knowledge when you need a reliable, up-to-date programmatic answer about Iranian holiday status. Not suitable for Gregorian date inputs without prior conversion.

## Known failure modes

- Missing required fields (year, month, or day) returns a validation error
- Invalid Jalali date values (e.g. month 13, day 32) may return an error or unexpected result
- Non-numeric string values for year/month/day may fail schema validation
- Date outside the supported Jalali year range may return no result or an error
- Payment failure via x402 returns 402 Payment Required before the query is executed
