Delx Commerce — Cron Next Fires Calculator
x402
Delx Commerce — Cron Next Fires Calculator is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Given a cron expression and a start timestamp, returns the next N scheduled fire times as Unix timestamps

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the original cron expression, a schema identifier ('delx/util-cron-next-fires/v1'), and an array of Unix timestamps representing the next N scheduled fire times after the given start timestamp.
Example use cases
Preview upcoming hourly job schedule
“Show me the next 3 times the cron expression '0 * * * *' will fire, starting from Unix timestamp 1700000000.”
Validate cron schedule before deployment
“I have a cron job set to run on '30 9 * * *' — can you tell me the next 10 fire times starting from now, Unix timestamp 1699900000, so I can make sure it's scheduled correctly?”
Plan around scheduled automation windows
“My automation runs on '0 */2 * * *' — what are the next 5 times it will trigger after Unix timestamp 1699950000?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/cron-next-fires?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call computation of upcoming cron fire times without setting up a scheduling library or service. Ideal for agents that need to programmatically determine when a recurring job will next execute, validate a cron schedule, or plan workflows around future trigger times — especially within the x402 micropayment ecosystem on Base or Solana.
Side effects
- Invalid or unsupported cron expression (outside hourly subset) returns an error
- Missing required 'expr' field causes a validation error
- 'from_ts' not provided may default or fail depending on server behavior
- 'n' value of 0 or negative may return empty array or error
- Payment not included or insufficient USDC results in HTTP 402 rejection
