Format Details

​
Raw HTML

Returns the complete, unmodified HTML source of the page. Parameter: raw_html=true Best for:
  • Full page preservation
  • Custom parsing and extraction
  • When you need exact page structure
Example output: 
<!DOCTYPE html>
<html>
<head>
  <title>Example Page</title>
  <script src="analytics.js"></script>
</head>
<body>
  <nav>...</nav>
  <main>
    <h1>Welcome</h1>
    <p>Content here...</p>
  </main>
  <footer>...</footer>
</body>
</html>

​
Enhanced HTML

Returns cleaned HTML with ads, tracking scripts, and unnecessary elements removed. Enabled by default. Parameter: enhanced_html=true (default) Best for:
  • Cleaner content processing
  • Reduced noise in extraction
  • When you want HTML structure without clutter
Example output: 
<main>
  <h1>Welcome</h1>
  <p>Content here...</p>
</main>

​
Plain Text

Returns extracted text content without any HTML markup. Parameter: page_text=true Best for:
  • Simple text processing
  • Search and analysis tasks
  • When HTML structure isn’t needed
Example output: 
Welcome

  • RAG pipelines

Recommendations by Use Case

Use Markdown format for optimal results:
  • Preserves document structure (headers, lists, links)
  • Minimal token usage
  • Clean content ready for embedding
response = requests.get(
    "https://api.crawleo.dev/crawl",
    params={"urls": url, "markdown": True},
    headers={"Authorization": f"Bearer {api_key}"}
)
Use Markdown or Plain Text:
  • Markdown if structure matters (enabled by default)
  • Plain text for maximum token efficiency
# For structured content (default)
params = {"urls": url, "markdown": True}

# For simple text
params = {"urls": url, "page_text": True, "markdown": False}
Use Raw HTML or Enhanced HTML:
  • Raw HTML for full control
  • Enhanced HTML for cleaner starting point (default)
# Get both formats
params = {"urls": url, "raw_html": True, "enhanced_html": True}
Use Plain Text or Markdown:
  • Easy to process with NLP tools
  • No HTML parsing required

​
Multiple Formats

You can request multiple formats in a single request: 
curl -X GET "https://api.crawleo.dev/crawl?urls=https://example.com&raw_html=true&enhanced_html=true&markdown=true&page_text=true" \
  -H "Authorization: Bearer YOUR_API_KEY"
The response will include all requested formats.
Pro tip: Markdown and Enhanced HTML are enabled by default. You only need to explicitly set parameters if you want to disable them or add additional formats.
