### Answer
As of now, there isn't a documented method for directly adding a knowledge base to an assistant via the POST request when creating it dynamically for each call. The option to add files is available through the Vapi dashboard, but there isn't a specified API endpoint for attaching these files to dynamically created assistants.
For now, you would need to manually manage the knowledge base through the dashboard and ensure that your dynamically created assistants have access to the same data.
For more detailed information on customizing the assistant's configuration, you can refer to the [Web Calling Quickstart Guide](
