[BUG] Superfluous parameters

[lkubb]

Description
Several functions in this extension take an api_version parameter, which is completely ignored.
The (superfluous) state module exposes a sound parameter, which is ignored.
The query utils func exposes token, which is ignored.

Steps to Reproduce the behavior
Set api_version to anything and see the extension still working.

Expected behavior
Don't expose parameters which do nothing.

There is only a single API version. We don't know how a successor will be structured, so we cannot assume the module code to just work. Only the query util func should retain the parameter for custom modules.
