How this service works
Parse a 5-field cron expression: get a plain-English explanation and the next N run times (UTC). POST { expression, count?, from? }.
Output
Returns a plain-English description of what the cron expression means and an ordered list of the next N UTC timestamps (up to 20) when the schedule will fire, optionally projected from a specified start date.
Example use cases
Debug a misconfigured cron job
“I set up a cron job with the expression '*/15 8-18 * * 1-5' but I'm not sure it's right — can you explain what it means in plain English and list the next 10 times it would fire starting from 2025-01-20T00:00:00Z?”
Verify a monthly billing schedule
“I want to confirm my billing job runs at the right time — the expression is '0 0 1 * *'. Can you explain it and show me the next 5 scheduled runs from today?”
Plan maintenance windows around a cron schedule
“Our deployment cron is '30 2 * * 0' — explain that schedule in plain English and give me the next 8 upcoming run times so I can plan around them.”
Technical details
Endpoint
POSThttps://coinslot.dev/api/cron?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to explain or validate a cron schedule in human-readable terms, or when you need to project future run times for planning, debugging, or auditing automation jobs. Prefer it over manual cron parsing or generic scheduling libraries when you want an instant, serverless, pay-per-use computation with no setup.
Side effects
- Invalid cron expression (wrong field count, illegal characters) returns a parse error
- Count outside allowed range 1–20 returns a validation error
- Malformed ISO date in 'from' field returns a date parse error
- Five-field expressions using non-standard syntax (e.g. seconds field) may not be supported
