How this service works
Call when an agent needs the next 8 UTC times for a 5-field cron expression. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/cron-next-5-8 first.
Output
Returns an ordered list of the next 8 UTC datetime timestamps at which the provided 5-field cron expression would fire, beginning at or after the specified 'from' datetime.
Example use cases
Verify weekday job schedule
“Can you tell me the next 8 times my cron job with expression '30 6 * * 1-5' will run, starting from now (2025-06-10T00:00:00Z)?”
Debug a monthly billing trigger
“I have a billing job set to run on the cron schedule '0 0 1 * *' — starting from 2025-07-01T00:00:00Z, what are the next 8 UTC times it will fire?”
Plan batch job timing for capacity planning
“We're running a data pipeline every 15 minutes with the expression '*/15 * * * *' — what are the next 8 execution times starting from 2025-06-15T08:00:00Z?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/cron-next-5-8?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to enumerate the next 8 future fire times for a standard 5-field Unix cron expression, particularly in scheduling verification, capacity planning, or automation orchestration workflows. Prefer the free sandbox variant (/v1/sandbox/cron-next-5-8) for testing. Choose this paid endpoint for production or when sandbox is unavailable.
Side effects
- Invalid cron expression (not a valid 5-field format) — likely returns a 400 error
- Malformed 'from' datetime that doesn't conform to ISO 8601 — parsing error
- Payment not included or rejected — 402 Payment Required (use sandbox endpoint for unpaid testing)
- Network or service unavailability — 5xx error
