How this service works
Time and schedule micro-tools for AI agents: UTC now, cron next-runs, timezone conversion, business-day math, and deadline checks. Pay with USDC via x402 — no API keys.
Output
Returns a JSON object with a 'next' array containing one or more ISO 8601 UTC datetime strings representing the upcoming execution times for the provided cron expression.
Example use cases
Scheduled report delivery timing
“My report job runs on cron '0 8 * * 1' — when does it next fire so I know when to expect the email?”
Verifying deployment window schedule
“We deploy with cron '0 2 * * 3', can you tell me the next three times that will trigger so I can plan my on-call rotation?”
Debugging a silent cron job
“Our cron '30 23 31 * *' seems to never run — can you calculate the next few scheduled times so I can see if it's actually valid?”
Technical details
Endpoint
POSThttps://agent-clock.annushka1190.workers.dev/v1/cron/nextWhen to prefer
Use this endpoint when an AI agent needs to programmatically determine the next scheduled run time(s) for a cron expression — ideal for automation pipelines, scheduling validation, devops tooling, or any workflow that needs to reason about future task timing without requiring an API key. Prefer it over general-purpose time APIs when the input is specifically a cron string.
Side effects
- Invalid or malformed cron expression returns an error response
- Missing required fields in the request body result in a 400-level error
- Extremely infrequent cron schedules (e.g. Feb 29 only) may return far-future dates
- x402 payment failure or insufficient USDC balance blocks the request
