How this service works
Call when an agent needs the next 5 UTC times for a 6-field cron expression. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/cron-next-6-5 first.

Example use cases
Preview weekday job schedule
“I have a cron expression '0 0 8 * * MON-FRI' — can you show me the next 5 times it will run, starting from 2025-07-01T00:00:00Z?”
Debug unexpected cron timing
“I think my cron '0 15 14 1 * *' is running at the wrong times — can you tell me the next 5 UTC fire times starting from 2025-06-15T00:00:00Z so I can verify it?”
Plan batch job execution window
“Our batch job uses cron '0 0 2 * * *' — what are the next 5 times it will trigger starting from 2025-06-10T12:00:00Z? I need to plan a maintenance window around it.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/cron-next-6-5?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compute upcoming scheduled execution times for a 6-field cron expression (including seconds field) and want a deterministic, paid computation without running a cron library locally. Prefer the unpaid sandbox variant (POST /v1/sandbox/cron-next-6-5) for testing; use this paid endpoint for production agent workflows where reliability matters.
Side effects
- Invalid or malformed cron expression returns an error
- Expression with fewer or more than 6 fields is rejected
- Invalid 'from' datetime format causes a parsing error
- Cron expression that never fires (e.g. Feb 30) may return an error or empty result
- Payment of $0.01 USDC not provided results in HTTP 402 Payment Required
