## 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 apexapi-cron-expression-parser-09291653 -d '<json body>'
```

Example prompt: Can you parse this cron expression for me and tell me what schedule it represents and when it will next run: '0 9 * * 1-5'?

## When to prefer this

Use this endpoint when you need to programmatically interpret, explain, or validate cron expressions for scheduling tasks — especially useful for developer tools, CI/CD pipelines, job schedulers, or any automation workflow that needs to surface next-run times or human-readable schedule descriptions to non-technical users.

## Known failure modes

- Invalid cron expression syntax returns an error with field-level detail
- Missing query parameter returns 400 bad request
- Overly complex or non-standard cron extensions may not be supported
- Payment failure via x402 returns 402 Payment Required
