There's the OWL API  (http://owlapi.sourceforge.net)

Pellet's native Ortiz API (http://weblog.clarkparsia.com/2010/12/17/ortiz-pellet/)

Any RDF API can work at the level triples that are used to encode OWL 2 objects.  However, this might be too low level for you.

Take a look at Clark and Parsia's StarDog software (http://stardog.com/).  It looks very comprehensive and Pellet is a key component.

See above.
