## 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 cron-expression-to-plain-english-translator-e94f630a
```

Example prompt: Can you tell me in plain English what this cron expression means: '0 9 * * 1-5'?

## When to prefer this

Use this endpoint when you need to display a cron schedule to a non-technical user, document a scheduled task in human-readable form, or verify that a cron expression encodes the intended recurrence. Prefer this over the companion /cron/next endpoint when you want a descriptive summary rather than concrete upcoming timestamps.

## Known failure modes

- Invalid or malformed cron expression returns an error response
- Missing 'expr' query parameter causes a 400-level error
- Non-standard or extended cron syntax (e.g. @yearly, 6-field with seconds) may not be supported or may return unexpected results

## How this service works

Translate a cron expression into plain English (e.g. "Every 15 minutes, weekdays") — the companion to /cron/next.

## Output

Returns a plain English string describing the cron schedule's recurrence pattern, such as 'Every 15 minutes on weekdays' or 'At 9:00 AM, Monday through Friday'. The response is a concise, human-readable interpretation of the cron expression's timing semantics.
