Claude Desktop Setup

Configure the Claude Desktop application to use TopRouter as the API provider.

Configuration File

Claude Desktop uses a JSON configuration file. Edit it to point to TopRouter:

macOS

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "apiBaseUrl": "https://toprouter.cc",
  "apiKey": "sk-your-toprouter-key"
}

Windows

Edit %APPDATA%\Claude\claude_desktop_config.json:

{
  "apiBaseUrl": "https://toprouter.cc",
  "apiKey": "sk-your-toprouter-key"
}

Steps

1. Close Claude Desktop completely
2. Open the config file at the path above (create it if it doesn't exist)
3. Add the configuration with your TopRouter API key
4. Save and restart Claude Desktop

WARNING

Make sure to use https://toprouter.cc without /v1 — Claude Desktop handles the path routing automatically.

Verify

After restarting, open Claude Desktop and send a test message. You should see responses from the TopRouter-routed model.

Troubleshooting

• No response: Check that the config file is valid JSON and the API key is correct
• Config file not found: Create the file at the path specified above
• Still using default provider: Make sure Claude Desktop was fully restarted (quit from system tray/dock)

TIP

Check your usage in the TopRouter Console to confirm requests are being routed through TopRouter.
