## 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 hebrew-date-converter-9b8b419b
```

Example prompt: What's the Hebrew calendar date for October 10, 2026? I need the day, month, and year in both English and Hebrew script.

## When to prefer this

Choose this endpoint when you need to convert a specific Gregorian date to its Hebrew calendar equivalent, especially when you need the result in Hebrew script. Ideal for Jewish observance apps, synagogue scheduling tools, genealogy research, or any use case requiring dual-calendar display. Prefer this over manual lookup tables or generic calendar libraries when you need a hosted, pay-per-call API with no setup.

## Known failure modes

- Missing or malformed 'date' query parameter returns an error
- Date outside supported Hebrew calendar range may return unexpected results
- Invalid date strings (e.g. '2025-13-45') may cause a 400 or error response
- Network or worker downtime causes 500 error
