How this service works

Parse a cron expression into a human-readable schedule description. Pass ?expr=<cron-expression> (URL-encoded). Also returns next 5 scheduled run times. Uses the 'cronstrue' npm package.

Output

A JSON response containing a human-readable description of the cron schedule (e.g. 'At 09:00 AM, Monday through Friday') and an array of the next 5 scheduled execution timestamps.

Example use cases

Example prompt

“Can you tell me in plain English what the cron expression '0 9 * * 1-5' means, and when it will next run?”

Technical details

Endpoint

POSThttps://httpay.xyz/api/cron-parse

When to prefer

Use this endpoint when an agent or user needs to understand what a cron expression means in human language or needs to preview upcoming run times without setting up a local cron parser library. Ideal for developer-facing workflows, scheduling UIs, or when validating cron job configurations. Pay-per-call via x402/USDC means no API key setup is required.

Side effects

Invalid or malformed cron expression returns an error
Missing 'expr' query parameter causes a 400-level error
Cron expression with unsupported fields (e.g. seconds or years in non-standard formats) may fail to parse
URL-encoding of the expression is required; unencoded special characters may cause parsing failures

Input

  "expr": "0 9 * * MON-FRI"
