How this service works
cron parser, cron expression parser, parse cron expression, cron parser online, cron schedule parser, crontab parser, cron syntax parser, cron decoder, cron validator, next run calculator, cron to human readable, crontab inspector, cron job parser. Parse 5-field cron expressions and compute next N execution times. Returns human description + upcoming timestamps. For AI agents, schedule debug, automation pipelines. Accepts payment on Base or Solana — either network works.
Output
Returns the original cron expression, a plain-English human-readable description of the schedule (e.g. 'At 09:00 AM, Monday through Friday'), the next N execution timestamps in ISO 8601 UTC format, and optionally a breakdown of the individual cron fields.
Example use cases
Debug scheduled automation job timing
“I have a cron job that's supposed to run every Friday at 3 PM, but I'm not sure if it's set up right. Can you decode the expression '0 15 * * 5' and show me the next few times it will actually execute?”
Validate infrastructure backup schedule
“Our backup script uses this cron expression: '0 2 * * 0'. Can you tell me what that means in plain English and confirm when the next 3 backups will run?”
Translate crontab for team documentation
“I need to explain our monitoring cron schedule to the team. Can you parse '*/30 * * * *' and give me a simple description of what it does, plus show me the next 10 execution times?”
Technical details
Endpoint
GEThttps://api.x402node.dev/dev/cron-parseWhen to prefer
Use this endpoint when you need to programmatically interpret, validate, or debug a 5-field cron expression, or when you need to compute future execution times for scheduling logic in automation pipelines, infrastructure config validation, or user-facing schedule displays. Prefer this over manual parsing when you need both a human-readable explanation and concrete upcoming timestamps in a single call.
Side effects
- Invalid cron expression (wrong number of fields, illegal values) — likely returns 4xx with error message
- Cron expression with unsupported syntax (e.g. 6-field with seconds) — may return parse error
- Missing required body parameter — returns 400 bad request
- Network timeout or service unavailability — returns 5xx
