@exalabs webSearch Tool
Search with Exa AI SDK's webSearch tool and Anthropic Claude Sonnet 4.5. Uses @exalabs/ai-sdk for seamless integration.
Use this when you want Exa search in an agent without defining any tool yourself, by importing the ready-made webSearch tool from @exalabs/ai-sdk.

Compare with
Similar patterns, and when each one is the better fit.
Search - Exa AI (robust)FreeUse this when you want Exa search split into separate tools for news, Reddit, Wikipedia, and URLs, so the model picks the right source.
Exa Web Search ToolUse this when you want to define the Exa search tool yourself with the Exa SDK and control how results are trimmed before reaching the model.
Claude Web Search ToolUse this when you need web lookups inside streamText on Anthropic without adding a separate search API, using Claude's provider-native search tool.
Web Search ToolUse this when you want OpenAI's built-in web_search_preview tool forced on every query so answers are grounded in live web results.
