How this service works
Call when an agent needs the next 12 UTC times for a 5-field cron expression. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/cron-next-5-12 first.
Output
Returns a list of exactly 12 UTC datetime timestamps representing the next scheduled occurrences of the given 5-field cron expression, starting from the specified 'from' datetime.
Example use cases
Preview weekday morning job schedule
“I have a cron expression '30 6 * * 1-5' and I want to see the next 12 times it will run in UTC starting from today, June 9th 2025 at midnight.”
Verify monthly billing job timing
“Can you show me the next 12 UTC fire times for the cron '0 0 1 * *' starting from 2025-07-01T00:00:00Z so I can confirm our billing job runs on the right days?”
Debug irregular cron trigger cadence
“I'm not sure my cron '*/15 9-17 * * 1,3,5' is set up correctly — can you compute the next 12 UTC times it would fire starting from 2025-06-10T09:00:00Z so I can check the pattern?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/cron-next-5-12?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to preview or validate an exact cron schedule by computing real UTC fire times, especially when automating scheduling decisions, verifying job cadences, or building calendar-aware workflows. Prefer the free sandbox endpoint /v1/sandbox/cron-next-5-12 for testing; use this paid endpoint for production use cases requiring reliability.
Side effects
- Invalid cron expression (wrong number of fields, illegal characters) returns an error
- Malformed 'from' datetime (not ISO 8601 / date-time format) returns a validation error
- Cron expression with no valid future occurrences (e.g. impossible schedule) may return an error or empty result
- Payment failure or insufficient USDC balance results in 402 response
