How this service works

Parse and explain any Unix cron expression in plain English. Returns human-readable schedule description, field breakdown, and the next N run times (UTC). Supports @yearly/@monthly/@weekly/@daily/@hourly shortcuts. Zero external calls.

Output

Returns an ordered list of upcoming scheduled run timestamps (ISO 8601) based on the provided cron expression, defaulting to 5 results and computing from now or a given reference time. Supports standard 5-field cron syntax and shortcuts like @daily, @hourly.

Example use cases

Example prompt

“What are the next 10 run times for the cron expression '0 9 * * 1-5', starting from 2025-06-01T00:00:00Z?”

Endpoint

GEThttps://the-stall.intuitek.ai/cap/cron-parser

When to prefer

Choose this endpoint when an AI agent needs to compute future scheduled times for a cron expression without requiring an account, API key, or server-side job runner. Ideal for lightweight, one-off schedule computations in automation pipelines, workflow builders, or developer tools that accept micropayments via USDC on Base. Prefer this over rolling your own cron library when the agent operates in a stateless or sandboxed environment.

Side effects

Invalid cron expression (malformed fields or out-of-range values) returns a parsing error
Missing required 'expression' query parameter returns a 400 or validation error
next_runs exceeding the maximum of 20 may be clamped or rejected
Invalid ISO 8601 format for from_iso returns a timestamp parsing error
Payment failure or insufficient USDC balance results in HTTP 402 response
