+The `get_balance` function is central to this workflow. It retrieves the user's balance based on the provided **username** and **password**.
 
 The key consideration here is that both username and password should **NEVER** be exposed to the LLM. Instead, they will be securely injected into the `get_balance` function later in the workflow using the [**`inject_params`**](../../../api/fastagency/api/code_injection/inject_params.md) mechanism, ensuring that sensitive information remains confidential while still allowing the function to access the required data.
