Claude Code Setup Guide

Install and configure the Claude Code CLI to connect to CodyRouter.

Claude Code is Anthropic's official CLI coding assistant. This guide walks you through installation and configuration.

Step 1: Install Claude Code

Open Terminal, PowerShell, or CMD, then run:

npm install -g @anthropic-ai/claude-code

If you hit permission issues on macOS or Linux, use sudo:

sudo npm install -g @anthropic-ai/claude-code

Verify Installation

claude --version

If a version number is shown, Claude Code is installed successfully.

Step 2: Set Environment Variables

Claude Code needs two environment variables to connect to CodyRouter:

• ANTHROPIC_BASE_URL: service endpoint
• ANTHROPIC_AUTH_TOKEN: your API key

Replace YOUR_API_KEY with the API key copied from the dashboard, choose your system, then copy the command into Terminal and press Enter.

macOS / Linux (zsh)

cat >> ~/.zshrc << 'EOF'
export ANTHROPIC_BASE_URL="https://api.codyrouter.com/"
export ANTHROPIC_AUTH_TOKEN="YOUR_API_KEY"
EOF
source ~/.zshrc

macOS / Linux (bash)

cat >> ~/.bashrc << 'EOF'
export ANTHROPIC_BASE_URL="https://api.codyrouter.com/"
export ANTHROPIC_AUTH_TOKEN="YOUR_API_KEY"
EOF
source ~/.bashrc

Windows PowerShell

[Environment]::SetEnvironmentVariable("ANTHROPIC_BASE_URL", "https://api.codyrouter.com/", "User")
[Environment]::SetEnvironmentVariable("ANTHROPIC_AUTH_TOKEN", "YOUR_API_KEY", "User")

Replace YOUR_API_KEY with an API key copied from the dashboard.
