## Installation

You can install the A2A SDK using either `uv` or `pip`.

## Prerequisites

- Python 3.10+
- `uv` (optional, but recommended) or `pip`

### Using `uv`

When you're working within a uv project or a virtual environment managed by uv, the preferred way to add packages is using uv add.

```bash
uv add a2a-sdk
```

### Using `pip`

If you prefer to use pip, the standard Python package installer, you can install `a2a-sdk` as follows

```bash
pip install a2a-sdk
```

## Examples

### [Helloworld Example](https://github.com/google-a2a/a2a-samples/tree/main/samples/python/agents/helloworld)

1. Run Remote Agent

   ```bash
   git clone https://github.com/google-a2a/a2a-samples.git
   cd a2a-samples/samples/python/agents/helloworld
   uv run .
   ```

2. In another terminal, run the client

   ```bash
   cd a2a-samples/samples/python/agents/helloworld
   uv run test_client.py
   ```

You can also find more Python samples [here](https://github.com/google-a2a/a2a-samples/tree/main/samples/python) and JavaScript samples [here](https://github.com/google-a2a/a2a-samples/tree/main/samples/js).
