Prerequisites Reminder
- An Unbound account with an API key
- The Unbound-modified version of Roo Code (not the standard VS Code marketplace version)
”Invalid API Key” Error
| Check | Fix |
|---|---|
| Wrong API provider | Ensure you selected “unbound” as the API provider, not “OpenAI” or “Anthropic” |
| Stale key | Copy the API key fresh from Connect → AI Coding Tools → Roo Code |
| Extra spaces | Check there are no extra spaces in the key |
| Cached session | Restart VS Code after changing settings |
| Wrong version | Verify you’re using the Unbound-modified Roo Code, not the marketplace version |
”Has Roo Code Discontinued Unbound as a Provider?”
No. If you don’t see the “unbound” provider option in the dropdown, you’re using the standard marketplace version of Roo Code. You need the Unbound-modified version. How to fix:- Uninstall the standard Roo Code extension from VS Code
- Contact your admin for the correct installation link for the Unbound-modified version
- Install the Unbound version
- Restart VS Code and configure using the Roo Code Integration guide
Connection Errors
Configure corporate proxy
If behind a corporate proxy, configure proxy settings in VS Code: File → Preferences → Settings → search “proxy”.
Credits Exhausted (Not an API Key Issue)
If you get a 402 error, your API key is valid but your credits are used up. See Credits & Budget for resolution steps.Verifying the Connection
After setup, send a simple test message in Roo Code. If you get a response from the AI, the integration is working correctly. If you see an error, check the Roo Code output panel for detailed logs:Still Having Issues?
