omnifetch-lib 1.3.0

Universal content extraction library with tiered fetching strategies and anti-bot bypass

OmniFetch Python Library

Python implementation of OmniFetch - a universal content extraction library.

Features

• Universal Extraction: Fetches content from any URL, handling standard sites, SPAs, and paywalls.
• Tiered System:
  1. Light Fetch: Fast, standard HTTP request.
  2. Headless Browser: Handles dynamic JS-heavy sites (requires Netlify endpoint).
  3. Search Fallback: Finds alternative sources for paywalled or blocked content.
• Smart Parsing: Converts HTML to clean Markdown or JSON.

Installation

pip install omnifetch-lib

Quick Start

from omnifetch import omni_fetch

# Text extraction (Markdown)
result = omni_fetch('https://example.com', mode='TEXT')
print(result.content)

# JSON extraction (Structured Data)
json_result = omni_fetch('https://example.com', mode='JSON')
print(json_result.content['title'])

Configuration

def omni_fetch(
    url: str,
    mode: str = 'TEXT',           # 'JSON' for structured, 'TEXT' for markdown
    timeout: int = 30,            # Request timeout in seconds
    netlify_endpoint: str = None, # Headless browser endpoint (Tier 2)
    headers: dict = None,         # Custom headers
    skip_headless: bool = False,  # Skip Tier 2
    skip_search: bool = False,    # Skip Tier 3
    force_title: str = None       # Override title for search fallback
) -> OmniFetchResult

Advanced Usage

Handling Blocked Domains (e.g., X/Twitter)

Some domains block direct scraping. OmniFetch automatically handles this by falling back to search (Tier 3). For opaque URLs, you can provide a force_title to improve search results.

result = omni_fetch(
    'https://x.com/someuser/status/12345',
    mode='TEXT',
    force_title='Specific Tweet Content Title' # Helps find the content via search
)

Headless Browser Support

To enable Tier 2 (Headless Browser) for dynamic sites, you need to deploy the provided Netlify function and pass the endpoint.

result = omni_fetch(
    'https://dynamic-site.com',
    netlify_endpoint='https://your-site.netlify.app/.netlify/functions/headless-fetch'
)
