Query molecule names

I would like to have a name associated with every molecule in my database. However, some imported molecules don't come with a name, so I have to generate one. From the top of my head I thought that maybe I'd check for common names, then (if there's none) I'd query an IUPAC name.
Firstly: Do you think this is a valid idea? Or would you discourage taking this route?
Secondly: Scouring through the Indigo API I noticed there is no functionality to help me in this endeavour (except a handful of abbreviations) - is this correct? If so, do you have a recommendation by any chance?

Thanks!
