How this service works
Crypto, AI, Social Media, Finance, Weather, Tools & more. Pay per call in USDC on Base. No API keys.
Output
Returns a structured object containing the human-readable interpretation of the cron expression, a list of upcoming scheduled execution times, field-by-field breakdown (minute, hour, day, month, weekday), and whether the expression is valid or contains errors.
Example use cases
Debugging a misconfigured cron job
“I have a cron expression '*/15 8-18 * * 1-5' set up on my server — can you parse it and tell me exactly what schedule it runs on and when the next few executions will be?”
Understanding inherited scheduled task
“Someone left this cron string in the codebase: '0 0 1,15 * *' — what does it actually mean in plain English and how often will it fire?”
Validating a newly written cron schedule
“I just wrote the cron expression '30 6 * * 0,6' for a weekend job — can you validate it and confirm it's correct, and tell me when it will next trigger?”
Technical details
Endpoint
POSThttps://nexus-api-virid.vercel.app/api/tools/cron/parserWhen to prefer
Use this endpoint when you need to programmatically interpret, validate, or explain cron expressions — especially useful in DevOps pipelines, scheduling automation agents, or when helping non-technical users understand inherited job schedules. Prefer this over manual parsing or regex approaches when you need accurate next-run times and a plain-English breakdown without building custom cron logic.
Side effects
- Invalid or malformed cron expression returns a validation error
- Overly complex or non-standard cron syntax (e.g. seconds field, @reboot) may not be supported
- Empty or missing query input returns a bad request error
- Ambiguous expressions (e.g. with timezone indicators) may be interpreted as UTC by default
