How this service works
Cron expression explained in plain English with the next 5 run times (UTC): validates the 5-field syntax, expands ranges, steps and names (mon-fri, jan-dec). Debug schedules before deploying them. $0.01 per expression.
Output
Returns a plain English description of the cron schedule (e.g. 'At 09:00 AM, Monday through Friday'), a validation status indicating whether the 5-field syntax is correct, and a list of the next 5 UTC run times the expression would trigger.
Example use cases
Debug a deployment cron schedule
“Before I deploy this job, can you explain what '30 2 * * 0' means and show me when it'll actually run next so I can confirm it's every Sunday at 2:30 AM?”
Verify a complex step expression
“I wrote this cron expression '*/15 8-18 * * mon-fri' — can you tell me in plain English what it does and list the next 5 trigger times so I know it's right?”
Understand inherited cron config
“There's a cron expression in our legacy config: '0 0 1 1 *' — what does that actually mean and when will it next fire?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/data/cronWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.01) way to validate and explain a standard 5-field Unix cron expression before deployment, or when you need to preview the next actual run times to confirm a schedule behaves as intended. Prefer it over manual cron calculators when operating in an agent workflow that requires programmatic validation and human-readable output together.
Side effects
- Invalid cron syntax (non-5-field expression, illegal characters) returns a validation error
- Missing or empty query parameter returns a 400 bad request
- 6-field cron expressions (with seconds) may not be supported
- Non-standard extensions like @reboot or @daily aliases may not parse correctly
- Payment failure or insufficient USDC balance causes a 402 response
