INTEGRATION GUIDE
Cline
Standalone agentsConfigure Cline's OpenAI Compatible provider for a standalone ZRouter gateway.
Compatibility first
Standalone gateway only for agent workflows. Cline uses tools and structured tool results. These are rejected by the current prepaid API, even with customer BYOK enabled.
Prepare a standalone deployment, an enabled tool-capable model, and a dedicated managed gateway key.
Configure the extension
Open Cline's settings using its gear icon. Choose OpenAI Compatible, then enter:
| Field | Value |
|---|---|
| Base URL | https://STANDALONE_GATEWAY_HOST/v1 |
| API key | Your dedicated managed ZRouter key |
| Model ID | Exact PROVIDER_INSTANCE/MODEL_ID returned by the gateway |
| Max output tokens | A limit supported by the selected model |
| Context window | The selected model's actual context limit |
Use OpenAI Compatible, rather than assuming the native OpenAI provider offers the same custom URL settings. Only enable image or computer-use capabilities when supported by the selected provider. See Cline's official provider setup.
Verify
Save the settings and use Verify if available. Start a small task, such as reading one file and explaining it. Check gateway logs for successful inference and tool exchanges. Tools run under Cline's permission controls; routing through ZRouter does not replace those controls.
Troubleshooting
- For authentication errors, use the managed gateway key, not the upstream provider key or an operator master key.
- For 404, the base URL should end at
/v1, not/v1/chat/completions. - For unknown models, copy the gateway's exact identifier instead of a display label.
- For
tools is not supported, the endpoint is using prepaid billing and cannot currently serve Cline agent sessions.
