The get_container_details() method provides low-level connection information for the currently active sandbox container. It returns a dictionary containing the container subdomain and playground access token, which are used internally to establish and maintain a secure WebSocket connection between your client and Fermion’s backend infrastructure.

​
get_container_details() -> Optional[dict[str, str]]

Description:
Returns container connection details, including the subdomain and secure access token.
If no sandbox is currently connected, returns None.
Parameters:
None
Returns: 
{
  "subdomain": str,
  "playground_container_access_token": str
} or None
Example 
from fermion_sandbox import Sandbox

sandbox = Sandbox(api_key="your-api-key")
sandbox.create(should_backup_filesystem=False)

details = sandbox.get_container_details()

if details:
    print("Subdomain:", details["subdomain"])
    print("Access Token:", details["playground_container_access_token"])
else:
    print("No active container connection.")
The access token is sensitive. Do not expose it in logs or UI.
