How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
A JSON object containing the original input description, the generated cron expression string, a plain-English explanation of what the expression means, and an array of upcoming scheduled execution timestamps.
Example use cases
Daily digest job scheduling
“I need a cron expression for sending a daily digest email at 7am every weekday — give me the crontab syntax and confirm the next few times it will run.”
Recurring data pipeline setup
“What's the cron expression for running a data pipeline twice a day, once at midnight and once at noon? Show me the expression and explain what each field means.”
Monthly report automation
“I want to schedule a monthly report on the 1st of each month at 6am — can you give me the correct crontab expression and tell me the next three execution times?”
Technical details
Endpoint
GEThttps://klymax402.com/api/crontab-generator/api/generateWhen to prefer
Choose this endpoint when you need to programmatically convert human-readable schedule descriptions to cron syntax without requiring a developer to manually construct the expression. Ideal for AI agents building automation pipelines, onboarding users into scheduled tasks, or validating that a natural language schedule maps to the intended cron timing. At $0.003/call it is cost-effective for high-volume schedule generation.
Side effects
- Ambiguous schedule description may produce an incorrect or approximate cron expression
- Very complex or irregular schedules (e.g. 'every other Tuesday except holidays') may not map cleanly to standard cron syntax
- Empty or missing description field returns an error
- Payment failure (insufficient USDC balance) blocks the request with a 402 response
