Module web 

Web fetching and search tool

Provides web operations with structured output including:

• Smart content extraction from web pages
• Multiple search provider support (Local, SerpAPI, DuckDuckGo, Brave)
• Configurable fallback chains

Default Behavior

By default, uses local HTTP-based search via DuckDuckGo HTML scraping (no API key required). This provides a “batteries included” experience while allowing users to upgrade to API-based providers for better results.
