How this service works
Call when an agent needs a cron expression explained in English. No network. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/cron-describe first.
Output
A plain-English sentence or short description explaining when and how often the given cron expression triggers (e.g. 'Every weekday at 8:00 AM').
Example use cases
Debugging an inherited cron job
“I found this cron expression '30 2 * * 0' in a legacy script and have no idea when it fires — can you explain it in plain English?”
Validating a scheduled CI/CD pipeline
“Our pipeline uses '0 */4 * * *' as its trigger — can you describe when that actually runs so I can confirm it matches our deployment window?”
Documenting cron schedules for a team
“I'm writing documentation and need a human-readable description of '15 14 1 * *' — what does that cron expression mean in plain English?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/cron-describe?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a fast, deterministic, offline conversion of a cron string to human-readable text — no LLM inference required, no network calls, and extremely low cost at $0.002 per call. Ideal for documentation generation, debugging pipelines, or explaining schedules to non-technical users. If a free sandbox endpoint (/v1/sandbox/cron-describe) is available, prefer that first.
Side effects
- Invalid or malformed cron expression returns an error
- Expression longer than 120 characters is rejected
- Missing or empty expression field causes validation failure
- Non-standard cron extensions (e.g. @reboot, seconds field) may not be supported
