Web search is now available on our API.

Developers can augment Claude's comprehensive knowledge with up-to-date data.

With web search enabled, Claude uses its own reasoning to determine whether a search would help inform a more accurate response.

Claude can also operate agentically and conduct multiple searches, using earlier results to inform subsequent queries. anthropic.com/news/web-searc…
