I'm not really familiar with the commerical SSH products (the free ones
do everthing I need). There are free Perl and Python SSH implementations
that might help you and there is libssh2[1] which appears to be a C API.
(I haven't tried any of these.)

If you are making lots of calls, then you could maintain a persistant
ssh connection and fire off transfers using the connection sharing
facilities. That way each transfer does not incur the cost of a key
exchange. See the ControlPath and ControlMaster options in "man
ssh_config" for more info.
