## Tools (2)

- `web_fetch_exa`: Read a webpage's full content as clean markdown. Use after web_search_exa when highlights are insufficient or to read any URL.

Best for: Extracting full content from known URLs. Batch multiple URLs in one call.
Returns: Clean text content and metadata from the page(s).
- `web_search_exa`: Search the web for any topic and get clean, ready-to-use content.

      Best for: Finding current information, news, facts, people, companies, or answering questions about any topic.
      Returns: Clean text content from top search results.

      Query tips:
      describe the ideal page, not keywords. "blog post comparing React and Vue performance" not "React vs Vue".
      Use category:people / category:company to search through Linkedin profiles / companies respectively.
      If highlights are insufficient, follow up with web_fetch_exa on the best URLs.
