How this service works
Call when an agent needs the next 1 UTC time for a 6-field cron expression. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/cron-next-6-1 first.
Output
Returns the next UTC datetime at which the given 6-field cron expression will fire, computed from the provided 'from' starting datetime. The response includes a single timestamp representing the upcoming trigger time.
Example use cases
Weekday morning job scheduling
“I have a cron job with the expression '0 0 8 * * MON-FRI' — starting from right now (2025-06-16T06:00:00Z), what's the next UTC time it will trigger?”
Validate next deploy window
“Our deployment pipeline uses the cron expression '0 15 2 1 * *' — can you tell me the next time it will run after 2025-06-01T00:00:00Z?”
Remind me of next scheduled report
“My automated report runs on '0 0 12 ? * SUN' — what's the next UTC datetime it fires after 2025-06-13T12:00:00Z?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/cron-next-6-1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to calculate the next single occurrence of a 6-field cron expression from a given UTC starting time, especially in automated pipelines, scheduling agents, or task orchestration systems. Prefer the free sandbox endpoint (/v1/sandbox/cron-next-6-1) for testing; use this paid endpoint for production or when the sandbox is unavailable. Choose this over standard 5-field cron calculators when your schedule uses a seconds field (6-field format).
Side effects
- Invalid cron expression format returns an error (e.g. wrong number of fields, unsupported syntax)
- Malformed or missing 'from' datetime causes a validation error
- Edge cases like unreachable cron schedules (e.g. Feb 30) may return an error or null
- Payment failure or insufficient USDC balance results in HTTP 402
