# Claude Code

> Claude Code Client Integration Guide

## 1. Install Node.js (Skip if installed)

Ensure Node.js version ≥ 18.0

<Tabs>
  <Tab title="Windows">
    Download: [https://nodejs.org/dist/v22.18.0/node-v22.18.0-x64.msi](https://nodejs.org/dist/v22.18.0/node-v22.18.0-x64.msi)
  </Tab>

  <Tab title="macOS">
    ```bash theme={null}
    sudo xcode-select --install
    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
    brew install node
    node --version
    ```
  </Tab>

  <Tab title="Ubuntu / Debian">
    ```bash theme={null}
    curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo bash -
    sudo apt-get install -y nodejs
    node --version
    ```
  </Tab>
</Tabs>

### Uninstall Other Proxy Clients (Optional)

Check installation:

```bash theme={null}
npm ls @anthropic-ai/claude-code
npm ls -g @anthropic-ai/claude-code
```

Uninstall:

```bash theme={null}
npm uninstall @anthropic-ai/claude-code
npm uninstall -g @anthropic-ai/claude-code
```

## 2. Install Claude Code

```bash theme={null}
npm install -g @anthropic-ai/claude-code
```

Verify installation:

```bash theme={null}
claude --version
```

## 3. Get API Key

```
base_url = "https://api.leapx-hub.com"
api_key = "sk-zbTYx*******************************fceTvn5"
```

## 4. Configure Environment Variables

### Basic Configuration Example

<Tabs>
  <Tab title="Mac / Linux">
    ```bash theme={null}
    export ANTHROPIC_BASE_URL="https://api.leapx-hub.com"
    export ANTHROPIC_AUTH_TOKEN="sk-zbTYx*******************************fceTvn5"
    export ANTHROPIC_MODEL="kimi-k2-250905"
    cd your-project-folder
    claude
    ```
  </Tab>

  <Tab title="Windows CMD">
    ```cmd theme={null}
    set ANTHROPIC_BASE_URL=https://api.leapx-hub.com
    set ANTHROPIC_AUTH_TOKEN=sk-zbTYx*******************************fceTvn5
    set ANTHROPIC_MODEL=kimi-k2-250905
    cd your-project-folder
    claude
    ```
  </Tab>

  <Tab title="Windows PowerShell">
    ```powershell theme={null}
    $env:ANTHROPIC_BASE_URL="https://api.leapx-hub.com"
    $env:ANTHROPIC_AUTH_TOKEN="sk-zbTYx*******************************fceTvn5"
    $env:ANTHROPIC_MODEL="kimi-k2-250905"
    cd your-project-folder
    claude
    ```
  </Tab>
</Tabs>

### Dual Model Configuration

Claude Code uses a dual-threaded model architecture by default:

* **Main Thread Model**: Configured via `ANTHROPIC_MODEL` environment variable
  * Used for primary code generation, conversations, and complex task processing

* **Secondary Thread Model**: Configured via `ANTHROPIC_DEFAULT_HAIKU_MODEL` environment variable
  * Purpose: Lightweight / fast-task model
  * Use cases:
    * Background tasks (file monitoring, linter checks, etc.)
    * Quick responses (simple questions, completion suggestions)
    * Low-priority auxiliary tasks

### Basic Configuration (Dual Model, Recommended)

<Tabs>
  <Tab title="Mac / Linux">
    ```bash theme={null}
    export ANTHROPIC_BASE_URL="https://api.leapx-hub.com"
    export ANTHROPIC_AUTH_TOKEN="sk-zbTYx*******************************fceTvn5"
    export ANTHROPIC_MODEL="kimi-k2-250905"
    export ANTHROPIC_DEFAULT_HAIKU_MODEL="claude-haiku-4-5-20251001"
    cd your-project-folder
    claude
    ```
  </Tab>

  <Tab title="Windows CMD">
    ```cmd theme={null}
    set ANTHROPIC_BASE_URL=https://api.leapx-hub.com
    set ANTHROPIC_AUTH_TOKEN=sk-zbTYx*******************************fceTvn5
    set ANTHROPIC_MODEL=kimi-k2-250905
    set ANTHROPIC_DEFAULT_HAIKU_MODEL=claude-haiku-4-5-20251001
    cd your-project-folder
    claude
    ```
  </Tab>

  <Tab title="Windows PowerShell">
    ```powershell theme={null}
    $env:ANTHROPIC_BASE_URL="https://api.leapx-hub.com"
    $env:ANTHROPIC_AUTH_TOKEN="sk-zbTYx*******************************fceTvn5"
    $env:ANTHROPIC_MODEL="kimi-k2-250905"
    $env:ANTHROPIC_DEFAULT_HAIKU_MODEL="claude-haiku-4-5-20251001"
    cd your-project-folder
    claude
    ```
  </Tab>
</Tabs>

### Single Model Configuration (Optional)

If you only need to use a single model, there are two configuration methods:

**Method 1: Configure both environment variables to the same model**

Set both `ANTHROPIC_MODEL` and `ANTHROPIC_DEFAULT_HAIKU_MODEL` to the same model (for example, both use `kimi-k2-250905`):

<Tabs>
  <Tab title="Mac / Linux">
    ```bash theme={null}
    export ANTHROPIC_BASE_URL="https://api.leapx-hub.com"
    export ANTHROPIC_AUTH_TOKEN="sk-zbTYx*******************************fceTvn5"
    export ANTHROPIC_MODEL="kimi-k2-250905"
    export ANTHROPIC_DEFAULT_HAIKU_MODEL="kimi-k2-250905"
    cd your-project-folder
    claude
    ```
  </Tab>

  <Tab title="Windows CMD">
    ```cmd theme={null}
    set ANTHROPIC_BASE_URL=https://api.leapx-hub.com
    set ANTHROPIC_AUTH_TOKEN=sk-zbTYx*******************************fceTvn5
    set ANTHROPIC_MODEL=kimi-k2-250905
    set ANTHROPIC_DEFAULT_HAIKU_MODEL=kimi-k2-250905
    cd your-project-folder
    claude
    ```
  </Tab>

  <Tab title="Windows PowerShell">
    ```powershell theme={null}
    $env:ANTHROPIC_BASE_URL="https://api.leapx-hub.com"
    $env:ANTHROPIC_AUTH_TOKEN="sk-zbTYx*******************************fceTvn5"
    $env:ANTHROPIC_MODEL="kimi-k2-250905"
    $env:ANTHROPIC_DEFAULT_HAIKU_MODEL="kimi-k2-250905"
    cd your-project-folder
    claude
    ```
  </Tab>
</Tabs>

**Method 2: Switch main thread model after startup**

Keep environment variables configured as in "Basic Configuration (Dual Model)". After starting Claude Code, in the interactive interface, enter:

```
/model haiku
```

The main thread will switch to use the model configured by `ANTHROPIC_DEFAULT_HAIKU_MODEL` (i.e., `claude-haiku-4-5-20251001`).
