Claude Code

Sign in, open API keys and click Create key. Copy it right away: it’s shown once. New to Modelway? Start with getting access.

Open PowerShell and run Anthropic’s installer. You don’t need to run it as Administrator.

irm https://claude.ai/install.ps1 | iex

With WinGet:

winget install Anthropic.ClaudeCode

Open a new terminal and check that it worked with claude --version, which prints a version number.

Optional. Install Git for Windows so Claude Code can run commands in Git Bash. Without it, it uses PowerShell.

Claude Code reads %USERPROFILE%\.claude\settings.json. Create the folder if it doesn’t exist yet, then open the file in an editor:

1New-Item -ItemType Directory -Force "$env:USERPROFILE\.claude"
2notepad "$env:USERPROFILE\.claude\settings.json"

Paste this in, with your key in place of the placeholder:

1{
2  "env": {
3    "ANTHROPIC_BASE_URL": "https://modelway.vip",
4    "ANTHROPIC_AUTH_TOKEN": "<your Modelway API key>",
5    "CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY": "1",
6    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1",
7    "CLAUDE_CODE_AUTO_MODE_SERVER": "0"
8  }
9}

If the file already has settings, add these entries to its env block instead.

Open a new terminal in a project folder and run:

claude

It opens without asking you to log in. Switch models with /model.

Run Preferences: Open User Settings (JSON) in VS Code and add:

1{
2  "claudeCode.environmentVariables": [
3    {
4      "name": "ANTHROPIC_BASE_URL",
5      "value": "https://modelway.vip"
6    },
7    {
8      "name": "ANTHROPIC_AUTH_TOKEN",
9      "value": "<your Modelway API key>"
10    }
11  ]
12}
