How this service works
Parses any standard cron expression and computes its next 1-20 firing times in a chosen timezone, flagging malformed expressions clearly rather than letting a bad schedule silently fail in production. For scheduler tooling, CI pipelines, and agents that generate cron syntax and need to sanity-check it.
Output
Returns a list of upcoming firing timestamps (up to 20) for the given cron expression in the requested timezone, or a clear error message describing exactly why the expression is malformed.
Example use cases
Example prompt
“Can you check this cron expression for me — '*/15 9-17 * * 1-5' — and show me the next 10 times it'll fire in America/Chicago timezone so I can confirm the schedule is right before I deploy it?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/crontab-next-run-timeWhen to prefer
Use this endpoint when you need to preview, validate, or sanity-check a cron expression before using it in a scheduler, CI pipeline, or automation tool — especially when the expression was generated programmatically and may contain errors. Ideal for agents that produce cron syntax and need to confirm correctness or when debugging an existing schedule.
Side effects
- Malformed cron expression returns a descriptive validation error rather than silently failing
- Invalid IANA timezone string causes an error indicating the unrecognized timezone
- Count out of range (beyond 20) may default or return an error
- Network timeout or service unavailability returns a generic HTTP error
