yycode Quick Start Guide

Prerequisite: Install the Node.js Environment

Claude Code depends on the Node.js runtime. Please first follow the Node.js Environment Installation Guide to install and verify it.

Easier Option: Automatic Configuration

If you do not want to manually install tools and write configuration item by item, we recommend using the Automatic Configuration Tool directly.

1. Configure Claude Code

Step 1: Install Claude Code

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

If you encounter permission issues on macOS / Linux, add sudo:

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

Verify the installation:

claude --version

Step 2: Create an API Key

Log in to the yycode console, go to Token Management, and click Add Token.

Enter a key name, select a group (model and multiplier), and optionally configure IP restrictions, quota limits, model restrictions, and expiration time. Beginners are advised to use the default settings.

Security note: An API Key is equivalent to account credentials. Keep it safe and never commit it to a code repository or share it publicly.

Step 3: Import the Key into Claude Code

Click the Copy button next to the key to obtain the API Key.

You need to set the following two environment variables:

Temporary setup (valid for the current terminal session)

Windows (PowerShell):

$env:ANTHROPIC_BASE_URL = "https://yycode.net"
$env:ANTHROPIC_AUTH_TOKEN = "YOUR_API_KEY"

macOS / Linux:

export ANTHROPIC_BASE_URL="https://yycode.net"
export ANTHROPIC_AUTH_TOKEN="YOUR_API_KEY"

Persistent setup (still valid after restart)

Windows (PowerShell):

[System.Environment]::SetEnvironmentVariable("ANTHROPIC_BASE_URL", "https://yycode.net", [System.EnvironmentVariableTarget]::User)
[System.Environment]::SetEnvironmentVariable("ANTHROPIC_AUTH_TOKEN", "YOUR_API_KEY", [System.EnvironmentVariableTarget]::User)

macOS (Zsh):

echo 'export ANTHROPIC_BASE_URL="https://yycode.net"' >> ~/.zshrc
echo 'export ANTHROPIC_AUTH_TOKEN="YOUR_API_KEY"' >> ~/.zshrc
source ~/.zshrc

Linux (Bash):

echo 'export ANTHROPIC_BASE_URL="https://yycode.net"' >> ~/.bashrc
echo 'export ANTHROPIC_AUTH_TOKEN="YOUR_API_KEY"' >> ~/.bashrc
source ~/.bashrc

Step 4: Start Using

Enter any project directory and run:

claude

Claude Code will automatically analyze the code in the current directory and provide intelligent programming assistance.

FAQ

Q: npm install -g reports insufficient permissions. What should I do?
A: On macOS / Linux, add sudo before the command. On Windows, run PowerShell as Administrator.

Q: claude --version says the command does not exist.
A: Make sure the npm global directory has been added to the system PATH. You can run npm bin -g to view the path and add it manually.

Q: Connection failed or a 401 error is returned.
A: Check whether ANTHROPIC_BASE_URL is https://yycode.net, and whether ANTHROPIC_AUTH_TOKEN is correct and has not expired.

Q: How do I switch between different models or multipliers?
A: Create keys for different groups in the yycode console) and use CC Switch to switch quickly between multiple configurations.
