# Tavily Comparison Project

This project demonstrates how to integrate the **Tavily API** to compare three entities. It performs a search query and summarizes the top results using the official Tavily SDK.

## Prerequisites

- Node.js (v18 or newer)
- A Tavily API key. Sign up at https://tavily.com and obtain your key.

## Installation

```bash
# Clone the repository
git clone https://git.brojs.ru/kuzakhmetovartur/povtornyy-ekzamen-2-sravnitelnyy-obzor-3.git
cd povtornyy-ekzamen-2-sravnitelnyy-obzor-3

# Install dependencies
npm install
```

## Configuration

Create a `.env` file in the project root with your Tavily API key:

```env
TAVILY_API_KEY=your_api_key_here
```

## Usage

Run the application:

```bash
npm start
```

You should see output similar to:

```
[OtherService] Starting search for: Comparison of three entities
[OtherService] Results:
1. Title of first result
   Summary of the first result.

2. Title of second result
   Summary of the second result.

3. Title of third result
   Summary of the third result.
```

## Project Structure

- `src/index.js` – Entry point that starts the application.
- `src/app.js` – Orchestrates the main flow.
- `src/services/tavily.js` – Wrapper around the Tavily SDK.
- `src/services/otherService.js` – Simple logging utility.
- `package.json` – Project metadata and dependencies.

## Notes

- The application uses the official `tavily-sdk` package.
- No additional external services are used beyond Tavily.
- The code is written in ES modules (`"type": "module"` in `package.json`).

Feel free to extend the project with more sophisticated logic or additional services as needed.
