Automatically monitor websites for content changes. This Actor uses a fast Cheerio crawler to compare page content across runs and notifies when changes are detected. Ideal for tracking notices, updates, pricing changes, and announcements.

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

1. Fetches the website using a Cheerio crawler
2. Extracts text or HTML from the full page or a selected section
3. Generates a hash of the extracted content
4. Compares the hash with the previous run
5. 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"
}
