Does Grok have real-time web search? How it works

Grok, xAI’s AI assistant, supports real-time retrieval from the web and public X posts through built-in tools, allowing it to cite sources and provide current information beyond its May 2026 knowledge cutoff. Its DeepSearch agent, introduced with Grok 3 in February 2025, gathers and evaluates information to generate concise reports, while developers can access web_search and x_search through the xAI API. Web search API calls cost $5 per 1,000 requests plus tokens, and X Search has separate charges for fetched posts and profiles; users can also apply limited domain filters, though Grok may still produce confident inaccuracies. The Exa team presents its search API as a portable alternative that works across Grok, Claude, GPT, and Gemini, costs $7 per 1,000 requests, and can be connected to Grok through Remote MCP tools or the Grok Build marketplace.
