Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 cron-parser-api-d80702e3
```

Example prompt: When will the cron expression '0 9 * * 1-5' run next — give me the next 10 occurrences in America/New_York time.

## When to prefer this

Use this endpoint when you need to programmatically parse a cron expression and retrieve concrete future run timestamps, especially when timezone awareness is important. Prefer this over manual cron calculators when an agent needs to verify a schedule, generate human-readable next-run previews, or validate that a cron expression behaves as expected.

## Known failure modes

- Invalid cron expression returns an error describing the parse failure
- Unsupported or misspelled IANA timezone returns a timezone error
- Count exceeding 20 may be capped or return a validation error
- Missing expression parameter results in a bad request error

## How this service works

Parse a cron expression and get next run times

## Output

A list of upcoming scheduled run timestamps (up to 20) derived from the parsed cron expression, returned in the specified IANA timezone. Useful for verifying cron schedules and understanding when jobs will execute.
