Does Claude have real-time web search? How it works
Blog post from Exa
Claude supports real-time web search across its applications, API, and Claude Code, allowing it to retrieve current information, fetch provided URLs, and cite sources in search-grounded responses. Anthropic’s system can autonomously determine when current information is needed or be directed through prompts, while users can enable the feature manually in some chat interfaces and organizations may need to activate it through administrative settings. In the API, developers add a web search tool and can control search limits and domain restrictions, with search priced at $10 per 1,000 queries plus token costs, while web fetching incurs token costs only. Claude Code includes WebSearch and WebFetch tools, although Bedrock users may need external integrations. The piece also presents Exa as an alternative search provider that can connect through MCP, supplying concise source highlights intended to conserve context-window capacity and offering full-page retrieval when needed.
