I'd like to set the application that should be run when a URL with a

_LSSetDefaultSchemeHandlerURL, but I'd rather not go with an
undocumented API if it can be avoided. Is there a Cocoa API or
something for this that I haven't been able to find? Or would I be
better off using the Cocoa APIs to modify the launch services
database
directly?
There is no Cocoa API. The only supported way of doing this is to
use LSSetDefaultHandlerForURLScheme(), which requires Tiger or
later. Prior to Tiger, you had to use Internet Config to do that.
Do you really need to set the default handler? Generally, Mac
applications merely advertise that they are capable of handling a
given URL scheme and it's left to the user to pick the default
handler. To merely advertise the capability, see the documentation
of the CFBundleURLTypes key of the Info.plist file:
