The source

The most useful number on your home screen is usually one nobody publishes. A self-hosted dashboard, a temperature sensor, a queue depth, a nightly job’s last run — all of them already return JSON to something. Zync just gives that number a permanent spot.

The result format

Pick the fields you want by their JSON path, and embed them between braces. A literal \n breaks the line; everything else is copied as written.
