## 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-4d291ea2 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when an agent or user needs to quickly decode, validate, or humanize a cron expression without running a local parser. Ideal when the runtime environment lacks cron libraries or when a plain-English explanation is needed for non-technical users.

## Known failure modes

- Invalid cron expression syntax returns an error response
- Missing or empty query field returns a 400 bad request
- Ambiguous or non-standard cron syntax (e.g. 6-field with seconds) may not parse correctly
- Network or upstream service failure returns a 5xx error
- Payment failure or insufficient USDC balance returns a 402

## How this service works

## Output

Returns a parsed breakdown of the cron expression including a human-readable description of the schedule, the next scheduled run times, and an explanation of each cron field (minute, hour, day, month, weekday).
