How this service works
Validates a cron expression and lists its next several scheduled run times as ISO timestamps in any timezone, so you can confirm a schedule does what it's supposed to before deploying it. For automation and DevOps agents building or auditing recurring jobs.
Output
Returns a list of N upcoming ISO 8601 timestamps (default 5) representing the next scheduled run times of the given cron expression, computed in the requested IANA timezone. Allows the caller to visually verify the schedule fires at the intended times before deployment.
Example use cases
Example prompt
“Check whether the cron expression '*/15 9-17 * * 1-5' is valid and show me the next 10 scheduled run times in America/New_York timezone so I can confirm it only fires on weekday business hours.”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/cron-schedule-checkerWhen to prefer
Use this endpoint when you need to programmatically validate a cron expression and preview its upcoming run times before deploying a scheduled job, or when auditing existing schedules for correctness across timezones. Prefer this over manual cron parsing tools when operating in an automated agent workflow that requires reliable, timezone-aware schedule verification at low cost.
Side effects
- Invalid cron expression returns an error indicating the expression could not be parsed
- Unrecognized IANA timezone string returns an error or falls back to UTC
- Missing expression field returns a validation error
- Non-numeric or negative count value may be rejected or clamped
- Payment failure (insufficient USDC balance) results in 402 response before processing
