Example: Web Search

The WebSearchTool demonstrates how to integrate external APIs into your agent’s toolset. This example implementation supports multiple providers like Tavily and Serper.

Configuration

The web search tool typically requires an API key for a search provider (e.g., Tavily, Serper).

#![allow(unused)]
fn main() {
use std::env;

env::set_var("TAVILY_API_KEY", "your-api-key");
}

Usage

use mojentic::prelude::*;
use mojentic::tools::WebSearchTool;
use std::sync::Arc;

#[tokio::main]
async fn main() -> Result<()> {
    // Initialize broker
    let gateway = Arc::new(OllamaGateway::new());
    let broker = LlmBroker::new("qwen3:32b", gateway, None);

    // Register the tool
    let tools: Vec<Arc<dyn LlmTool>> = vec![
        Arc::new(WebSearchTool::new(SearchProvider::Tavily)),
    ];

    // Ask a question requiring up-to-date info
    let messages = vec![
        LlmMessage::user("What is the current stock price of Apple?"),
    ];

    let response = broker.generate(&messages, Some(tools), None).await?;
    println!("{}", response);
    
    Ok(())
}

Supported Providers

• Tavily: Optimized for LLM agents
• Serper: Google Search API
• DuckDuckGo: Privacy-focused search (no API key required for basic usage)
