In PSX there are two controllers which help you to build an API. The 
PSX\\Controller\\HandlerApiAbstract and PSX\\Controller\\SchemaApiAbstract 
controller. If you want build fast an API from an existing data source i.e. an 
sql table you should use the :doc:`handler` controller. If you want create a 
long term API with fine control over the input you should choose the 
:doc:`schema` controller.
