## 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 exchangerebel-devutils-cron-expression-parser-117da774
```

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

Choose this endpoint when you need a quick, programmatic way to parse and explain a cron expression in plain English — especially useful in developer tooling pipelines, documentation generators, or debugging workflows where understanding an existing schedule is the goal. Prefer this over building a cron parser locally when low-latency, pay-per-call pricing is acceptable.

## Known failure modes

- Invalid or malformed cron expression returns an error or empty result
- Missing required query parameter causes a 400-level error
- Cron expressions with non-standard extensions (e.g. seconds field, @reboot) may not be supported
- Network timeout on slow connections

## How this service works

devutils-cron-parse

## Output

Returns a structured response containing a human-readable description of the cron schedule (e.g. 'At 9:00 AM, Monday through Friday'), the individual field meanings (minute, hour, day-of-month, month, day-of-week), and a list of upcoming next execution timestamps based on the parsed expression.
