What This Actor Does

Monitors any website for content changes
Supports full-page or CSS selector–based monitoring
Compares current content with previous runs
Outputs a simple changed / not changed status
Designed as a reusable API and automation

How It Works

Fetches the website using a Cheerio crawler
Extracts text or HTML from the full page or a selected section
Generates a hash of the extracted content
Compares the hash with the previous run
Reports whether a change was detected

Input

This Actor accepts the following input parameters:

url (required):
The website URL that should be monitored for changes.
selector (optional):
A CSS selector to monitor only a specific part of the webpage, such as a notice section or content container.
checkType (optional):
Defines whether text content or raw HTML should be monitored.
Possible values are text (default) and html.

Example Input

{
  "url": "https://example.com/notice",
  "selector": ".announcements",
  "checkType": "text"
}

## Output

Each run produces a dataset entry with the result of the change check:

- **url**:  
  The monitored website URL.

- **changed**:  
  A boolean value indicating whether the content has changed since the previous run.

- **checkedAt**:  
  An ISO timestamp indicating when the website was checked.

### Example Output

```json
{
  "url": "https://example.com/notice",
  "changed": true,
  "checkedAt": "2025-01-01T12:30:00.000Z"
