## 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 nexusapi-cron-expression-parser-d514a707 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need to programmatically interpret, validate, or explain cron expressions — especially useful in DevOps pipelines, scheduling automation agents, or when helping non-technical users understand inherited job schedules. Prefer this over manual parsing or regex approaches when you need accurate next-run times and a plain-English breakdown without building custom cron logic.

## Known failure modes

- Invalid or malformed cron expression returns a validation error
- Overly complex or non-standard cron syntax (e.g. seconds field, @reboot) may not be supported
- Empty or missing query input returns a bad request error
- Ambiguous expressions (e.g. with timezone indicators) may be interpreted as UTC by default
