## 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 primeapi-cron-expression-parser-8ffe64bb -d '<json body>'
```

Example prompt: Can you parse this cron expression for me — '0 9 * * 1-5' — and tell me in plain English when it runs and what the next 3 scheduled times will be?

## When to prefer this

Use this endpoint when you need to programmatically parse, validate, or explain cron job expressions without setting up a local parsing library. Ideal for AI agents helping developers understand or debug scheduled tasks.

## Known failure modes

- Invalid cron expression format returns a validation error
- Missing query input returns a 400 bad request
- Ambiguous or non-standard cron extensions may not be supported
- Payment failure (402) if USDC payment not included or insufficient
