It's true there's no official API, but you can get an idea about best practices by reading other extensions, particularly those bundled with hg. For this particular problem, I would do something like this:

from mercurial import ui, hg
from mercurial.node import hex

repo = hg.repository('/path/to/repo/root', ui.ui())
fctx = repo.filectx('/path/to/file', 'tip')
hexnode = hex(fctx.node())

Update At some point the parameter order changed, now it's like this:

   repo = hg.repository(ui.ui(), '/path/to/repo/root' )
