How this service works
Pay-per-call utility APIs for AI agents, settled in USDC via the x402 protocol.
Output
A JSON object containing the original cron expression, the requested timezone, a human-readable plain-English description of the schedule (e.g. 'At 09:30 AM, Monday through Friday'), and an array of the next N ISO 8601 timestamps when the cron will fire.
Example use cases
Example prompt
“What does the cron expression '30 9 * * 1-5' mean, and when will it fire next — show me the next 5 run times in America/New_York time?”
Technical details
Endpoint
POSThttps://x402.nichospt.net/cron-describe?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to interpret or explain a cron expression to a user in plain language, preview upcoming scheduled job execution times, or validate that a cron string is well-formed and understand its cadence — especially when a per-call micropayment model via USDC is acceptable and the agent needs a lightweight, on-demand utility rather than a full scheduling platform.
Side effects
- Invalid cron expression (malformed fields, wrong number of fields) — returns error indicating parse failure
- Unsupported or misspelled IANA timezone string — returns timezone not recognized error
- Count exceeds maximum of 20 — returns validation error
- Payment not settled via x402 protocol — returns 402 Payment Required before processing
- Empty or missing cron field — returns required field missing error
