# Models

> Discover the AI detection models available to your API key

<Badge color="green">Current</Badge>

Use the Models API to discover the model selectors your API key can currently use. The catalog reflects both your account's entitlements and current model availability, so do not hard-code it or assume every API key sees the same models. Preserve the order returned by the server.

## GET /models

```
GET https://text.external-api.pangram.com/models
```

### Response

<ResponseField name="models" type="array[string]">
  Ordered model selectors currently available to the authenticated API key.
</ResponseField>

### Example

<CodeGroup>
  ```bash cURL theme={null}
  curl -X GET https://text.external-api.pangram.com/models \
    -H "x-api-key: $PANGRAM_API_KEY"
  ```

  ```python Python SDK theme={null}
  from pangram import Pangram

  client = Pangram()
  available_models = client.list_models()
  ```
</CodeGroup>

**Example Response**

```json theme={null}
{
  "models": [
    "default",
    "pangram-4"
  ]
}
```

Use one of the returned values as the request-wide `model` on [`POST /task`](/api-reference/ai-detection) or [`POST /bulk`](/api-reference/bulk-api). The `default` selector follows Pangram's current default model without pinning your integration to a numbered generation.
