# Watch a page: describe the change to report

Say in plain words what you care about, for example "tell me when a plan gets more expensive", "a new job in Berlin" or "back in stock". The monitor turns your sentence into conditions, ignores every change that does not match (layout, dates, banners), and reports only matching changes as facts: what changed, from what, to what, with both versions of the page. Numbers work too: "the Business plan costs more than $250". On treg's key it runs from your team's watch budget (crawl4ai.watch.budget.add).

## Example

```curl
curl -X POST 'https://toolswitch.dev/v1/tools/crawl4ai.watch.create' \
  -H "X-Toolswitch-Key: $TOOLSWITCH_KEY"
```
