## Before you start

- Create a Relyven key that can use the model you need.
- Copy the exact model ID from the dashboard.
- Update Cline if the current version does not show a custom provider or base URL.

## Configure the provider

Open Cline settings, choose the custom OpenAI-compatible provider, and enter:

```text
Base URL: https://api.relyven.com/v1
API key:  your Relyven key
Model ID: an exact model ID shown in the dashboard
```

Save the provider and start a new task. Setting labels can differ between Cline versions; follow the current Cline interface when a label has changed.

## Verify text and tools

Send a short request first. Then run a task that reads a small local project or uses another safe tool. A text reply confirms basic generation, while the second test checks tool events.

## Troubleshooting

| Result | Check |
|---|---|
| `401` | API key and `https://api.relyven.com/v1` |
| `403` | Model permission on the key |
| `400` | Selected provider type, model ID, and tool schema |
| Model list is stale | Reopen Cline and copy the current model ID from the dashboard |
| Old provider still runs | Start a new Cline task after saving the provider |
