# Query model configuration details

Read model selection, capabilities and reference information for an agent model configuration.

```text
GET https://moi.matrixorigin.cn/newmoi/workspaces/{workspace_id}/model-configs/{model_config_id}
```

## Before you call

First [query the model configuration list](list-model-configurations.md) to obtain the configuration ID. Prepare a personal access token and target workspace ID that has access to the target workspace.

The example below uses:

- `$AI_STUDIO_API_KEY`: The actual personal access token, passed through the `X-API-Key` Header.
- `$WORKSPACE_ID`: Target workspace ID, passed through the `X-Workspace-ID` Header and also as `workspace_id` in the path.
- `$MODEL_CONFIG_ID`: The model configuration ID to query as `model_config_id` in the path.

## Request example

```bash
curl "https://moi.matrixorigin.cn/newmoi/workspaces/$WORKSPACE_ID/model-configs/$MODEL_CONFIG_ID" \
  -H "X-API-Key: $AI_STUDIO_API_KEY" \
  -H "X-Workspace-ID: $WORKSPACE_ID"
```

## Path parameters

| Parameters | Type | Is it required | Description |
| --- | --- | --- | --- |
| `workspace_id` | string | Yes | The current workspace ID. |
| `model_config_id` | string | Yes | Model configuration ID. |
