Chemaxon Molecule type information API

Use this service to get information about the molecule types. These types specify what to do with a structure during search. You can fine tune the search logic with different aromatization, tautomerization, standardization, fingerprint calculation settings, etc. You may define types in application.properties before starting the service.
