With the introduction of web search on the Anthropic API, developers can now build AI applications and agents that tap into current information from across the web without needing to manage their own web search infrastructure. Claude, a comprehensive knowledge model, uses its reasoning capabilities to determine whether searching the web would be beneficial for providing more accurate responses, generating targeted search queries, retrieving relevant results, and analyzing them for key information. This enables developers to power a wide range of use cases across various industries, such as financial services, legal research, developer tools, and productivity, with real-time data and specialized knowledge. Additionally, web search includes citations to source materials, ensuring accuracy and accountability, and provides admin settings to control domain allow lists, block lists, and organization-level management. The feature is also available in Claude Code, enhancing development workflows with current API documentation and technical articles.
