+# You.com Search Integration
+
+This directory contains examples demonstrating how to integrate You.com's search API with Deep Agents for enhanced web research capabilities.
+
+## Overview
+
+The You.com search integration provides high-quality web search results with source citations, offering an alternative to other search providers. It supports both authenticated and keyless usage modes.
+
+## Files
+
+- `tools/youcom-search.ts` - You.com search tool implementation
+- `youcom-search-agent.ts` - Simple example agent using You.com search
+- `research-agent.ts` - Enhanced research agent with both Tavily and You.com search options
+
+## Setup
+
+### Option 1: Keyless Mode (Basic)
+
+The You.com search tool works without any API key for basic search functionality:
+
+```typescript
+import { youcomSearch } from "./tools/youcom-search.js";
+
+// No environment variables needed for basic usage
+const agent = createDeepAgent({
+  model: new ChatAnthropic({ model: "claude-sonnet-4-20250514" }),
+  tools: [youcomSearch],
+});
+```
+
+### Option 2: Authenticated Mode (Enhanced)
+
+For enhanced features and higher rate limits, add your You.com API key:
+
+```bash
+# Add to your .env file
+YDC_API_KEY=your_youcom_api_key_here
+```
+
+Get your API key from [You.com API](https://api.you.com/?utm_source=deepagents&utm_medium=integration&utm_campaign=search_tool).
+
+## Usage Examples
+
+### Basic Web Search
+
+```typescript
+import { createDeepAgent } from "deepagents";
+import { youcomSearch } from "./tools/youcom-search.js";
+
+const agent = createDeepAgent({
+  model: new ChatAnthropic({ model: "claude-sonnet-4-20250514" }),
+  tools: [youcomSearch],
+  systemPrompt: "You are a research assistant with web search capabilities.",
+});
+
+const result = await agent.invoke({
+  messages: [new HumanMessage("What are the latest developments in AI?")],
+});
+```
+
+### Multi-Tool Research Agent
+
+```typescript
+import { youcomSearch } from "./tools/youcom-search.js";
+import { internetSearch } from "./research-agent.js"; // Tavily search
+
+const researchAgent = createDeepAgent({
+  model: new ChatAnthropic({ model: "claude-sonnet-4-20250514" }),
+  tools: [internetSearch, youcomSearch], // Multiple search providers
+  systemPrompt: `You have access to multiple search tools:
+    - internet_search: Tavily search with topic filtering
+    - youcom_search: You.com search with high-quality results`,
+});
+```
+
+### Tool Parameters
+
+The `youcom_search` tool accepts these parameters:
+
+- `query` (string, required): The search query
+- `maxResults` (number, optional, default: 5): Maximum number of results (1-20)
+- `includeRawContent` (boolean, optional, default: false): Include raw content (not currently implemented)
+
+## Features
+
+- **High-quality results**: You.com's search API provides curated, relevant results
+- **Source citations**: Results include titles, URLs, and snippets
+- **Flexible authentication**: Works with or without API keys
+- **Error handling**: Graceful handling of rate limits, authentication errors, and API issues
+- **TypeScript support**: Full type safety with Zod schema validation
+
+## Error Handling
+
+The tool handles common error scenarios:
+
+- **401 Unauthorized**: Invalid or missing API key
+- **429 Rate Limited**: Too many requests (try again later or add API key)
+- **402 Payment Required**: Quota exceeded (add API key for higher limits)
+- **Network errors**: Connection timeouts and other network issues
+
+## Integration with Deep Agents
+
+The You.com search tool follows Deep Agents conventions:
+
+- Uses the standard LangChain `tool()` function
+- Includes Zod schema for parameter validation
+- Returns formatted text results compatible with agent reasoning
+- Handles errors gracefully without breaking agent workflows
+
+## Running Examples
+
+```bash
+# Install dependencies
+pnpm install
+
+# Set up environment (optional for keyless mode)
+cp .env.example .env
+# Edit .env to add YDC_API_KEY if desired
+
+# Run the You.com search example
+npx tsx examples/research/youcom-search-agent.ts
+
+# Run the enhanced research agent with multiple search tools
+npx tsx examples/research/research-agent.ts
+```
+
+## API Reference
+
+### You.com Search API
+
+- **Endpoint**: `https://api.you.com/v1/agents/search`
+- **Authentication**: Bearer token (optional)
+- **Rate Limits**: Higher limits with API key
+- **Documentation**: [You.com API Docs](https://documentation.you.com/?utm_source=deepagents&utm_medium=integration&utm_campaign=search_tool)
+
+### Tool Schema
+
+```typescript
+{
+  query: string;           // Search query
+  maxResults?: number;     // Max results (1-20, default: 5)
+  includeRawContent?: boolean; // Include raw content (default: false)
+}
+```
+
+### Response Format
+
+The tool returns formatted search results as text:
+
+```
+Found 5 search results for "AI developments":
+
+1. **Latest AI Breakthroughs in 2024**
+   URL: https://example.com/ai-breakthroughs
+   Recent advances in AI include improved language models...
+
+2. **AI Research Trends**
+   URL: https://example.com/ai-trends
+   Researchers are focusing on multimodal AI systems...
+```
+
+## Best Practices
+
+1. **Use appropriate maxResults**: Start with 5 results, adjust based on needs
+2. **Handle errors gracefully**: The tool returns error messages as strings for agent processing
+3. **Combine with other tools**: Use alongside filesystem, memory, and other research tools
+4. **API key management**: Use environment variables, never hardcode keys
+5. **Rate limiting**: Be mindful of API limits, especially in keyless mode
+
+## Troubleshooting
+
+### Common Issues
+
+**"No search results found"**
+- Try rephrasing the query
+- Check internet connectivity
+- Verify the query is not too specific
+
+**"Rate limit exceeded"**
+- Add a YDC_API_KEY for higher limits
+- Wait before retrying
+- Reduce search frequency in agent workflows
+
+**"API authentication failed"**
+- Verify YDC_API_KEY is correct
+- Check environment variable is loaded
+- Ensure API key has proper permissions
