# List Models

> GET /v1/models. Returns the list of available models.

`GET /v1/models`

Returns the list of models currently available through Consus Gateway.

## Request

### Headers

| Header      | Required | Description  |
| ----------- | -------- | ------------ |
| `x-api-key` | Yes      | Your API key |

### Example

```bash theme={null}
curl https://api.consus.io/v1/models \
  -H "x-api-key: $CONSUS_API_KEY"
```

## Response

The response lists every requestable composite ID across all active models. Each base model expands into its full ladder of authorized levels (FedRAMP Low/Moderate/High plus DoD IL2/IL4/IL5 where applicable, with `+itar` variants when the underlying provider is ITAR authorized). ITAR-authorized models additionally list a standalone `:itar` ID (ITAR with no compliance level). The example below is truncated for readability.
