How this service works
Convert a cron expression to a human-readable description

Example use cases
Example prompt
“Can you explain what this cron expression means in plain English: '0 9 * * 1-5'?”
Technical details
Endpoint
POSThttps://cron.agentutil.net/v1/explainWhen to prefer
Use this endpoint when an AI agent or user needs to understand what a cron expression does in human terms — particularly useful for code review, documentation generation, debugging scheduled jobs, or explaining configuration to non-technical users. Prefer over manual parsing when the expression includes complex ranges, lists, or step values.
Side effects
- Invalid or malformed cron expression returns an error response
- Empty expression field causes validation failure
- 6-field or non-standard cron syntax may not be supported
- Network or upstream service unavailability
- Payment failure via x402 protocol blocks the request
