# users.get_by_username Get user by username Returns a user selected by exact username after applying READ_USER authority. include_deleted permits an authorized caller to inspect a permanent tombstone; it does not grant additional authority. Missing and unauthorized matches both return 404 so this guessable identifier cannot reveal whether a user exists. Args: username (str): Exact username include_deleted (bool, optional, default=False): Permit an authorized read of a permanent tombstone Returns: UserResponse ```python users.get_by_username(*, username: 'str', include_deleted: 'bool | None' = None) -> 'UserResponse' ``` [users](../users.md) · [Python](../../python.md)
