# Use `ListKeyspaces` with an AWS SDK
<a name="keyspaces_example_keyspaces_ListKeyspaces_section"></a>

The following code examples show how to use `ListKeyspaces`.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:
