# User Balance by Discord ID

{% hint style="info" %}
This endpoint relies on CARV ID to establish the relationship between the provided Discord ID and the corresponding blockchain address. If the specified discord\_user\_id is not connected to any address through CARV ID, the API will not be able to retrieve the expected result. Ensure that the Discord account is properly linked to a blockchain address via CARV ID before making a request.
