Python library which wraps radamsa and blab -- https://code.google.com/p/ouspg/w/list -- behind a simple and easy-to-use Python API...or at least tries to do that :-)
You'll probably need to do some modifications (at bare minimum you should update the blab and radamsa binaries and chmod +x them). You probably should not do anything too heavy duty with this, since this solution is suboptimal compared to using radamsa or blab directly, but it can be used to testing and as an example of one way of interfacing them I guess.
