## 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-jalali-to-gregorian-date-converter-1a7e2746 -d '<json body>'
```

Example prompt: Convert the Jalali date 1402/6/31 to its Gregorian equivalent — that's year 1402, month 6, day 31 in the Persian Solar Hijri calendar.

## When to prefer this

Choose this endpoint when you need a reliable, pay-per-call Jalali-to-Gregorian conversion with no signup or API key required. It is ideal for AI agents processing Iranian documents, scheduling systems that must interoperate between Persian and Western calendars, or any workflow dealing with Iranian government records, HR data, or historical research. Prefer this over building your own conversion logic when you need a hosted, maintained service with predictable per-call pricing in USDC.

## Known failure modes

- Invalid Jalali date (e.g., day 31 in a 30-day month) returns an error response
- Out-of-range year or month values cause validation failure
- Missing required fields (year, month, or day) result in a bad request error
- Non-numeric or malformed string inputs may cause parsing errors
- Payment failure via x402 will prevent the call from completing
