Is there an API to access my PoolParty thesaurus server?

Besides the standard SPARQL endpoint which can be used for each thesaurus to make queries over the knowledge model there is the PoolParty API to integrate the thesaurus in other systems (like search applications etc.). It provides a typical REST interface to access data from a thesaurus repository. PoolParty API provides methods like getTopConcepts which, for instance, returns a list of Top Concepts of a Concept Scheme in JSON format.
