Configure Environment Variables

Enter the following commands in your terminal to set environment variables for using AgentRouter's Anthropic API:

Linux/macOS

# Set AgentRouter's API base URL
export ANTHROPIC_BASE_URL=https://agentrouter.org/

# Set your AgentRouter API key, available at https://agentrouter.org/console/token
export ANTHROPIC_AUTH_TOKEN=sk-xxx
export ANTHROPIC_API_KEY=sk-xxx

Windows PowerShell

# Set AgentRouter's API base URL
$env:ANTHROPIC_BASE_URL="https://agentrouter.org/"

# Set your AgentRouter API key, available at https://agentrouter.org/console/token
$env:ANTHROPIC_AUTH_TOKEN="sk-xxx"
$env:ANTHROPIC_API_KEY="sk-xxx"

IMPORTANT

Make sure to replace sk-xxx with the Token provided by AgentRouter. You can get your API Key from the AgentRouter Console.

Launch Directly

After configuring the environment variables, use your terminal to open the project directory you want to work with, then run the following command to start Claude Code:

# Navigate to project directory
cd my-project

# Launch Claude Code directly
claude

TIP

You can add the environment variable configuration to your shell configuration file to avoid manual setup each time:

Linux/macOS

# Add to ~/.bashrc or ~/.zshrc file
export ANTHROPIC_BASE_URL=https://agentrouter.org/
export ANTHROPIC_AUTH_TOKEN=sk-xxx
export ANTHROPIC_API_KEY=sk-xxx

Windows PowerShell

# Add to PowerShell profile ($PROFILE)
$env:ANTHROPIC_BASE_URL="https://agentrouter.org/"
$env:ANTHROPIC_AUTH_TOKEN="sk-xxx"
$env:ANTHROPIC_API_KEY="sk-xxx"
