## 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 strale-crontab-generator-c17a79fd
```

Example prompt: Can you generate a cron expression for running a task every weekday at 8:30am?

## When to prefer this

Use this endpoint when an agent or user needs to programmatically generate crontab expressions from plain English schedule descriptions, or validate/parse existing cron expressions, without manually writing cron syntax. Prefer this over general-purpose LLM completions when you want a structured, auditable output with a cryptographic audit trail.

## Known failure modes

- Ambiguous or unrecognizable schedule description returns an error or low-confidence result
- Invalid cron expression syntax in input may return a parsing error
- Overly complex or contradictory schedules (e.g. 'every 7th minute on the 31st of February') may not be representable in standard cron format

## How this service works

Convert natural language schedule to cron expression, or explain an existing cron expression. Returns next run times.

## Output

A valid crontab entry or cron expression representing the requested schedule, derived from the natural language description or parsed cron input provided.
