What This Skill Does

The Web-Scraper skill is a powerful, versatile tool for OpenClaw that enables users to automate the extraction of structured data from almost any website. Whether you are performing market research, monitoring competitor pricing, aggregating real estate listings, or gathering job board data, this skill provides the necessary framework to turn unstructured HTML into clean, usable formats like JSON, CSV, or Excel. It supports both modern dynamic websites requiring browser-based rendering and lightweight static sites.

Installation

To integrate this skill into your environment, run the following command in your terminal:

clawhub install openclaw/skills/skills/sa9saq/web-scraper

Ensure you have the required dependencies, such as puppeteer and cheerio, installed in your project workspace, as the skill utilizes these libraries to perform headless browser automation and fast HTML parsing respectively.

Use Cases

• E-commerce Monitoring: Track product pricing, inventory levels, and customer reviews across multiple storefronts to optimize your own sales strategy.
• Real Estate Aggregation: Automatically collect property listings including pricing, area data, and contact information to create custom market reports.
• Job Market Analysis: Extract job titles, salaries, and company requirements to stay informed about industry trends.
• Social Media Sentiment Analysis: Monitor follower counts and engagement metrics to evaluate brand influence and performance.

Example Prompts

1. "Scrape the product names and prices from [URL] and save the results as a CSV file."
2. "Extract all job titles and salary ranges from this careers page: [URL]. Limit the search to the first 5 pages."
3. "Go to this real estate site, collect the property details, and format the output as a JSON object."

Tips & Limitations

• Ethics & Compliance: Always verify that your scraping activities comply with the target website's robots.txt file and terms of service. Do not attempt to access private or login-protected data.
• Performance: Use the HTTP/Cheerio method for static sites whenever possible to reduce resource consumption. Reserve the Puppeteer (browser-based) method for sites that rely heavily on JavaScript rendering.
• Data Integrity: Implement random delays in your scripts to mimic human behavior and avoid being blocked by anti-bot measures. Always ensure that the collected data is cleaned and normalized before being used for critical analysis.
