## 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 fastx402-lab-localized-date-formatter-14a70928
```

Example prompt: Format 2026-10-17T14:05:00 as a full date with the weekday name, day, month, year, and time in German — use the pattern EEEE, d MMMM yyyy HH:mm.

## When to prefer this

Use this endpoint when you need to render a date as a localized, human-readable string in one of five supported languages (English, Turkish, German, French, Spanish) using a flexible date-fns/Unicode pattern. Prefer it over generic date libraries when you need a simple, stateless API call for i18n date formatting without setting up a locale library in your environment.

## Known failure modes

- Missing required 'date' query parameter — returns error
- Missing required 'pattern' query parameter — returns error
- Invalid ISO 8601 date string — may return error or unexpected result
- Unsupported locale value outside en/tr/de/fr/es — returns validation error
- Invalid or malformed date-fns pattern — may return error or garbled output
- Payment not provided or insufficient — x402 payment required response

## How this service works
