## How It Works

**Instructions**

* Defines agent as research assistant
* Finds and summarizes information from web
* Provides comprehensive research results
* Maintains informative and helpful tone

**Tools**

* `DuckDuckGoTools()`: Search web for current information
* Web search integration for real-time data
* Information gathering and summarization

**Model**

* `gpt-4o-mini`: Cost-effective model for research tasks
* Via OpenRouter API integration
* Configurable through environment variables

**Payment**

* `execution_cost`: \$0.0001 USDC per request
* `base-sepolia` network for transactions
* Protected `message/send` method requires payment

## Dependencies

```bash theme={null}
uv init
uv add bindu agno python-dotenv
```

## Environment Setup

Create `.env` file:

```bash theme={null}
OPENROUTER_API_KEY=your_openrouter_api_key_here
```

## Run

```bash theme={null}
uv run premium-research-assistant.py
