How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
Returns a JSON object containing the original cron expression, the starting datetime, and an array of ISO 8601 UTC timestamps representing the next N scheduled run times (up to 20).
Example use cases
Preview weekday morning job schedule
“Show me the next 7 times this cron expression will fire: '0 9 * * 1-5', starting from today 2026-01-05T00:00:00Z.”
Verify monthly report timing
“I have a cron job set to '0 8 1 * *' — when will the next 5 runs happen starting from 2026-03-01T00:00:00Z?”
Debug overnight batch schedule
“My nightly batch job runs on '30 2 * * *' — can you show me the next 3 scheduled run times after 2026-06-10T00:00:00Z?”
Technical details
Endpoint
GEThttps://fastx402.tools/cron-next-runs?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly compute upcoming cron job fire times without setting up a cron library locally. Ideal for agents that need to preview, validate, or explain scheduled task timing to users, or to check if a schedule aligns with a desired recurrence pattern. Prefer this over running a full cron daemon or importing a cron parser library when a lightweight, pay-per-call API call suffices.
Side effects
- Invalid cron expression (malformed or wrong number of fields) returns an error
- Count outside 1-20 range may return an error or be clamped
- Malformed ISO 8601 datetime in 'after' field returns a parse error
- Missing required 'expression' query parameter returns a validation error
