## Retrieve

`policy_bundle.retrieve(PolicyBundleRetrieveParams**kwargs)  -> BinaryResponseContent`

**get** `/policy/bundle`

Returns the effective Policy Bundle for the user identified by the
zone-issued resource-scoped token. When no user-scope binding exists,
one will be generated from the default set.

The response body is a binary archive in the codec selected via the
`Accept` header. The only codec supported today is
`application/vnd.keycard.policy-bundle.v1+tar+gzip`. Clients SHOULD send
an explicit `Accept` header; absent one, the server defaults to the
tar+gzip codec.

Supports conditional fetch via `If-None-Match`: when the supplied ETag
matches the current bundle, the server responds `304 Not Modified` with
no body.

### Parameters

- `if_none_match: Optional[str]`

- `x_client_request_id: Optional[str]`

### Returns

- `BinaryResponseContent`

### Example

```python
import os
from keycardai_api import KeycardAPI

client = KeycardAPI(
    api_key=os.environ.get("KEYCARD_API_API_KEY"),  # This is the default and can be omitted
)
policy_bundle = client.policy_bundle.retrieve()
print(policy_bundle)
content = policy_bundle.read()
print(content)
```
