# Router Management Plane Models List API

> List all provider-attributed models exposed by the Aria Compute ROUTER management plane. Distinct from the OpenAI data plane /v1/models endpoint.

The management-plane Models endpoint returns the full list of models known to the Aria Compute ROUTER, annotated with their owning provider. This is separate from the OpenAI-compatible `/v1/models` data-plane endpoint. Use it to audit available models and their backend attribution.

Any authenticated caller may access this endpoint.

## Endpoint

```http theme={null}
GET /v1/router/models
```

## Authentication

Authenticate with a session cookie or pass `Authorization: Bearer <api-key>`.

## Response

<ResponseField name="items" type="array">
  List of provider-attributed models.

  <Expandable title="items">
    <ResponseField name="id" type="string">
      Model identifier.
    </ResponseField>

    <ResponseField name="provider" type="string">
      Name of the provider that serves this model.
    </ResponseField>

    <ResponseField name="backend_ref" type="string">
      Backend endpoint or identifier.
    </ResponseField>
  </Expandable>
</ResponseField>

<RequestExample>
  ```bash cURL theme={null}
  curl -X GET "https://router.example.com/v1/router/models" \
    -H "Authorization: Bearer <api-key>"
  ```
</RequestExample>

<ResponseExample>
  ```json 200 theme={null}
