# Installation

Grace Protocol provides a CLI and a REST API. Install the CLI to manage wallets, policies, and transactions from the command line.

***

## CLI

The CLI is the primary tool for managing wallets, policies, and transactions. It is open source and distributed as an npm package and a standalone binary.

### npm (recommended)

```bash
npm install -g @graceprotocol/cli
```

### Standalone binary

Download the latest release for your platform from [github.com/graceprotocol/cli/releases](https://github.com/graceprotocol/cli/releases).

**macOS (Apple Silicon)**

```bash
curl -fsSL https://graceprotocol.org/install.sh | sh
```

**macOS (Intel)**

```bash
curl -fsSL https://graceprotocol.org/install.sh | sh -s -- --arch amd64
```

**Linux**

```bash
curl -fsSL https://graceprotocol.org/install.sh | sh
```

**Windows**

Download the `.exe` from the releases page and add it to your `PATH`.

### Verify

```bash
grace --version
# graceprotocol/cli v1.0.0 darwin-arm64
```

***

## CI/CD environments

For non-interactive environments, set the API key as an environment variable:

```bash
export GRACE_API_KEY=rp_live_...
grace wallet balance --agent my-agent
```

The CLI reads `GRACE_API_KEY` automatically. No `grace auth login` step required.

***

## Updating

```bash
npm update -g @graceprotocol/cli
```

Or re-run the install script to get the latest binary.
