## 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 klymax402-cron-expression-parser-9e874254
```

Example prompt: Parse the cron expression '0 9 * * 1-5' and show me the next 10 scheduled run times in the America/Chicago timezone.

## When to prefer this

Use this endpoint when you need to quickly preview or validate a cron schedule without running a local cron parser, especially when you need timezone-aware results or want to inspect future execution times for debugging or documentation purposes.

## Known failure modes

- Invalid cron expression syntax returns an error or empty result
- Unrecognized IANA timezone string causes a validation error
- Count value exceeding max of 20 may be clamped or rejected
- Missing expression parameter results in a bad request error

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a list of upcoming scheduled datetime strings representing the next N times the provided cron expression will fire, computed relative to the current time in the requested IANA timezone.
