# Valyu Search

Search across the world's knowledge.

## When to Use

Trigger this skill when the user asks for:
- "search the web", "web search", "look up", "find online", "find papers on..."
- "current news about...", "latest updates on..."
- "research [topic]", "what's happening with...", "deep research on..."
- "extract content from [URL]", "scrape this page", "get the text from..."
- "answer this with sources", "what does the research say about..."
- Fact-checking with citations needed
- Academic, medical, financial, or patent research
- Structured data extraction from web pages

## Prerequisites

- Get an API key at [valyu.ai](https://www.valyu.ai)
- Set `VALYU_API_KEY` in the Gateway environment (recommended) or in `~/.openclaw/.env`.
