How this service works
Validate and describe a five-field cron schedule for $0.001 USDC, including the next runs. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns a validation status indicating whether the cron expression is syntactically valid, a human-readable description of the schedule (e.g. 'At 9:00 AM, Monday through Friday'), and a list of the next upcoming run timestamps based on the expression.
Example use cases
Debug a misfiring cron schedule
“I set up a cron job with the expression '*/15 8-18 * * 1-5' but I'm not sure it's right — can you validate it and tell me in plain English when it fires and show me the next few run times?”
Explain an inherited cron expression
“There's this cron string '0 0 1 * *' in our codebase and I have no idea what it does — can you describe what schedule it represents and when it will next trigger?”
Verify a nightly backup schedule
“I want to make sure my backup cron job '30 2 * * *' is set correctly to run at 2:30 AM every day — can you confirm it's valid and show me the upcoming runs?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/cronWhen to prefer
Choose this endpoint when you need a lightweight, no-API-key way to validate and explain a cron expression and see its next scheduled runs. It is particularly useful for agents building or debugging automation workflows, checking inherited schedules, or explaining cron syntax to non-technical users. Costs $0.001 USDC per call via x402 payment, making it cost-effective for occasional lookups.
Side effects
- Invalid or malformed cron expression returns a validation error with details about which field is incorrect
- Expressions with fewer or more than five fields are rejected
- Expressions using non-standard extensions (e.g. seconds field, @yearly aliases) may not be supported
- Network timeout or service unavailability returns an error
- Missing or insufficient payment (x402) results in a payment-required error
