The answer to the question posed is yes. There is indeed code available for the batch.xtz.tools platform. The code can be found on Github and is open source, meaning anyone can access and use it. The code is written in the Elixir programming language and is designed to help developers create and manage their own XTZ-based applications. It also provides a range of features such as account management, transaction management, and security. With the code, developers can create their own XTZ-based applications and services, allowing them to take advantage of the XTZ blockchain technology.
