VSCode Configuration

This guide will help you configure Claude Code extension in VSCode with Fizzly API.

Prerequisites

VSCode 1.80 or later
Claude Code extension installed
Fizzly API key (Get one here)

Install Claude Code Extension

Open VSCode
Go to Extensions (Ctrl+Shift+X / Cmd+Shift+X)
Search for “Claude Code”
Click Install

Configure Extension Settings

Open VSCode Settings (Ctrl+, / Cmd+,) and search for “Claude Code”:

Method 1: Settings UI

Find Claude Code: API Key
Enter your Fizzly API key
Find Claude Code: Base URL
Enter https://api.fizzlyapi.com

Method 2: settings.json

Press Ctrl+Shift+P / Cmd+Shift+P, type “Open Settings (JSON)”, and add:

{
  "claude-code.apiKey": "your-fizzly-api-key",
  "claude-code.baseUrl": "https://api.fizzlyapi.com"
}

Verify Configuration

Open Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
Type “Claude Code: Start”
Claude Code should start without errors

Workspace Configuration

For project-specific settings, create .vscode/settings.json in your project:

{
  "claude-code.baseUrl": "https://api.fizzlyapi.com",
  "claude-code.model": "claude-3-5-sonnet-20241022"
}

⚠️

Security Note: Don’t commit API keys to version control. Use environment variables or VSCode’s secure storage for API keys.

Recommended Settings

{
  "claude-code.baseUrl": "https://api.fizzlyapi.com",
  "claude-code.model": "claude-3-5-sonnet-20241022",
  "claude-code.maxTokens": 4096,
  "claude-code.temperature": 0.7
}

Using Environment Variables

You can also use environment variables with VSCode. The extension will automatically detect:

ANTHROPIC_API_KEY
ANTHROPIC_BASE_URL

This is useful for keeping secrets out of settings files.

Troubleshooting

Extension Not Working

Check extension is enabled in Extensions panel
Reload VSCode (Ctrl+Shift+P → “Developer: Reload Window”)
Check Output panel for errors (View → Output → Select “Claude Code”)

API Connection Failed

Verify API key is correct
Check Base URL is https://api.fizzlyapi.com
Ensure you have internet access
Check if firewall is blocking connections

Model Not Available

Verify model name is correct
Check your account has access to the model
Ensure sufficient balance in your account
