Web Scraper

Universal web scraping and data extraction through SandBase. Scrape individual pages, crawl entire sites, extract structured data, and capture visual snapshots. Read the API map before selecting a capability.

Call SandBase capabilities

For every selected tool, call sandbase_describe_tool first and use only arguments in its current input schema. Then call sandbase_call_tool with the exact tool_name.

Operating principles

• Respect robots.txt and rate limits — these tools handle that automatically.
• Use the lightest tool for the job: markdown scrape before full crawl.
• Structured data extraction is best for product pages, directories, and lists.
• Screenshots are useful for visual verification and design research.

Workflow

1. Single page extraction

Use context_dev_scrape_markdown for clean Markdown output (best for articles, docs). Use context_dev_scrape_html for raw HTML (best for structure analysis). Use firecrawl_scrape for advanced single-page extraction with options.

2. Site crawling

Use firecrawl_crawl to crawl multiple pages following links. Use firecrawl_map to discover all URLs on a site. Use context_dev_crawl_site for site-wide content extraction. Use context_dev_crawl_sitemap for sitemap-based crawling.

3. Structured data extraction

Use context_dev_extract_structured_data for custom schema extraction from pages. Use context_dev_extract_product for single product data. Use context_dev_extract_products for product listing pages.

4. Visual and metadata

Use context_dev_capture_screenshot for visual page snapshots. Use context_dev_scrape_images for image extraction. Use context_dev_scrape_fonts for typography analysis. Use context_dev_retrieve_brand for brand asset extraction.

Output

Return: extracted content in requested format, structured data as JSON, screenshot URLs, or crawl results with page list.
