# OpenVibe.Watch > Get told when a page, a price, a feed or an API changes, or when a channel goes live. Watch checks politely on your schedule and keeps every check. Every page is server-rendered and complete without JavaScript. A person signs in with OpenVibe.Network to define and manage their own watches; nobody else can see them. ## Start here - [OpenVibe.Watch](https://openvibe.watch/index.md): What Watch is and the four ways to start a watch. - [How it checks](https://openvibe.watch/how-it-works.md): The carrier order, the cadence floor and what each state means. ## For machines - [The watch API (for services)](https://openvibe.watch/how-it-works.md): Bearer tokens, one capability per route; /api/v1/* stays loopback-only. ## Optional - [Sitemap](https://openvibe.watch/sitemap.xml) - [Full text for language models](https://openvibe.watch/llms-full.txt) - [Release metadata (JSON)](https://openvibe.watch/release.json)
