### `ArgusClient.create()`

This class method is the designated constructor for creating an `ArgusClient` instance. It authenticates the API key and configures the client's default state.

**Signature:**

```
@classmethod
def create(
    cls,
    api_key: str,
    asset_id: Optional[str] = None,
    session_id: Optional[str] = None,
    policy: Optional[Policy] = None,
    save: bool = False,
    strict: bool = True,
    url: Optional[str] = None
) -> "ArgusClient"
```

**Parameters:**

| Parameter    | Type               | Default | Description                                                                                                                                                                                                             |
| :----------- | :----------------- | :------ | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `api_key`    | `str`              | (none)  | **Required.** Your Argus API key. The key's prefix determines the available feature set.                                                                                                                                |
| `asset_id`   | `Optional[str]`    | `None`  | **Platform Tier Only.** The default Asset ID to associate with all scans. An Asset is a logical container for policies and analytics in the Argus Platform. This parameter is ignored for non-platform keys.            |
| `session_id` | `Optional[str]`    | `None`  | **Platform Tier Only.** The default Session ID to associate with all scans. A Session groups related interactions for contextual analysis. This parameter is ignored for non-platform keys.                             |
| `policy`     | `Optional[Policy]` | `None`  | The default `Policy` object configuration to apply to all scans. This is the primary method for defining rules for non-platform users.                                                                                  |
| `save`       | `bool`             | `False` | **Platform Tier Only.** If `True`, all scan results are persisted in the Argus platform for analytics and log review. An `asset_id` must be provided to enable saving. This parameter is ignored for non-platform keys. |
| `strict`     | `bool`             | `True`  | If `True`, invalid client-side policy configurations (e.g., an empty list for a required parameter) will raise an `ArgusValueError`. If `False`, a `UserWarning` will be issued instead, and the scan may proceed.      |
| `url`        | `Optional[str]`    | `None`  | **Platform Tier Only.** The Base URL that can be used to perform scan in a self hosted argus environment.                                                                                                               |

**Returns:** An initialized `ArgusClient` instance.

**Exceptions:**

* `ArgusValueError`: If the `api_key` has an invalid format.
* `ArgusAuthenticationError`: If the `api_key` is invalid or expired.
* `ArgusNotFoundError`: If a provided `asset_id` does not exist.
