# Tavily integrations

> Integrate with Tavily using LangChain Python.

[Tavily](https://tavily.com) is a search engine specifically designed for AI agents, providing search, extract, crawl, and map APIs so developers can connect their applications to real-time online information. Tavily's primary mission is to deliver factual and reliable information from trusted sources, enhancing the accuracy and reliability of AI-generated content and reasoning.

The `langchain-tavily` package exposes Tavily's Search, Extract, Crawl, and Map endpoints as LangChain tools.

## Installation and setup

Install the Tavily integration package for LangChain Python:

<CodeGroup>
  ```bash pip theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
  pip install langchain-tavily
  ```

  ```bash uv theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
  uv add langchain-tavily
  ```
</CodeGroup>

[Set up a Tavily API key](https://app.tavily.com) and set it as an environment variable named `TAVILY_API_KEY`:

```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
export TAVILY_API_KEY="your-api-key"
```

## Tools
