description	Web search and content fetching using Linkup extension. Use when needing to search the web, get answers to questions with sources, or fetch content from specific URLs. Provides three tools: linkup_web_search (discovery), linkup_web_answer (direct answers), linkup_web_fetch (URL content extraction).

Linkup Extension

Web search and content fetching tools powered by Linkup API.

Tools

linkup_web_search

Search the web and get sources with content snippets.

linkup_web_search(query: string, depth?: "fast" | "standard" | "deep", limit?: number)

• query: Be specific and detailed. Include context like dates, locations, company names.
• depth: Search depth mode. Default: "standard".
  • fast: Sub-second latency, uses pre-indexed "atoms of information". Best for quick facts and simple lookups.
  • standard: Single iteration retrieval. Balanced speed and depth for most queries.
  • deep: Up to 10 iterations with chain-of-thought reasoning. Best for complex multi-step research (slower).
• limit: Maximum number of results. Default: 10.

Search result content is truncated per result. If a result is truncated, the tool output includes a temp file path with the full result content.

Use when: Discovering information across multiple sources, researching topics, comparing perspectives.

linkup_web_answer

Get a synthesized answer with source citations.

linkup_web_answer(query: string, depth?: "fast" | "standard" | "deep")

• query: Be specific and detailed.
• depth: Same depth modes as linkup_web_search. Default: "standard".

The answer and source snippets are truncated independently. If any block is truncated, the tool output includes a temp file path with the full block content.

Use when: Need a direct answer to a specific question, quick facts with citations.

linkup_web_fetch

Fetch content from a URL as clean markdown.

linkup_web_fetch(url: string, renderJs?: boolean)

• url: The URL to fetch.
• renderJs: Set false for static pages (faster). Default: true.

Fetched markdown is truncated when large. If it is truncated, the tool output includes a temp file path with the full markdown content.

Use when: Reading documentation, following up on search results, extracting content from known URLs.

Tool Selection

Need	Tool
Find information across sources	linkup_web_search
Get a direct answer with sources	linkup_web_answer
Read content from a known URL	linkup_web_fetch

Query Formulation

Good queries are specific:

Bad	Good
"Microsoft revenue"	"Microsoft fiscal year 2024 total revenue"
"React hooks"	"React useEffect cleanup function best practices"
"AI news"	"OpenAI announcements January 2026"

Add context:

• Time: "2025", "last quarter", "since version 5.0"
• Location: "French company Total", "US market"
• Specifics: company names, version numbers, exact terms

Depth Mode Selection

Fast: Sub-second responses for quick facts, simple lookups, known facts.

Standard (default): Single iteration, balanced speed/depth for most queries.

Deep: Complex research, multi-step queries, comprehensive coverage needed.

// Fast - instant facts, sub-second
linkup_web_search("Node.js 22 release date", depth: "fast")

// Standard - balanced, one search iteration
linkup_web_search("React useEffect cleanup best practices")

// Deep - complex research, multiple iterations
linkup_web_search("comparison of Rust web frameworks performance benchmarks 2025", depth: "deep")

Common Patterns

Research workflow

1. linkup_web_search to discover sources
2. linkup_web_fetch on promising URLs for full content

Quick facts

1. linkup_web_answer for direct answer with citations

Documentation reading

1. linkup_web_fetch on known documentation URL
