How this service works
Cron expression parser API: validate any cron expression and get its next N run times as ISO timestamps in any timezone. For scheduler-building and automation agents.
Output
Returns an array of the next N ISO 8601 timestamps representing when the cron expression will trigger, along with any validation feedback indicating whether the expression is syntactically correct.
Example use cases
Example prompt
“Can you parse the cron expression '0 9 * * 1-5' and show me the next 8 times it'll fire, in America/New_York timezone?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/parse-cron-expressionWhen to prefer
Use this endpoint when you need to validate a cron expression and preview its actual future fire times in a specific timezone, especially when building schedulers, automation workflows, or debugging why a cron job isn't running as expected. Prefer this over manual parsing when timezone-aware ISO timestamps are required.
Side effects
- Invalid cron expression syntax returns a validation error
- Unrecognized IANA timezone string causes a bad request error
- Count parameter out of acceptable range may return an error or be capped
- Malformed request body missing the expression field returns a 400-level error
