  3. Install SDK: Install the Linkup SDK using the command above.

​
Example

The following example demonstrates how to initialize the tool and use it in an agent:
Code
from crewai_tools import LinkupSearchTool
from crewai import Agent
import os

# Initialize the tool with your API key
linkup_tool = LinkupSearchTool(api_key=os.getenv("LINKUP_API_KEY"))

# Define an agent that uses the tool
@agent
def researcher(self) -> Agent:
    '''
    This agent uses the LinkupSearchTool to retrieve contextual information
    from the Linkup API.
    '''
    return Agent(
        config=self.agents_config["researcher"],
        tools=[linkup_tool]
    )

​
Parameters

The LinkupSearchTool accepts the following parameters:

​
Constructor Parameters

  • api_key: Required. Your Linkup API key.

​

  • depth: Optional. The search depth. Default is “standard”.
  • output_type: Optional. The type of output. Default is “searchResults”.

​
Advanced Usage

You can customize the search parameters for more specific results:
Code
# Perform a search with custom parameters
results = linkup_tool.run(
    query="Women Nobel Prize Physics",
    depth="deep",
    output_type="searchResults"
)

​
Return Format

The tool returns results in the following format: 
{
  "success": true,
  "results": [
    {
