Not yet through the API. We're working on OAuth support to provide
submission, digging, and so on.
>... i.e with a single URL that packs all the parameters needed.
Well, now, that sounds a lot like the submit link used by the "Digg
This" button (which is not part of the API):
http://digg.com/tools/integrate
But note "Digg This" requires user interaction. Fully-automated
submission isn't offerred.
Your description of the flow is accurate, yes.
Lots of web sites, including big mainstream media sites, use "Digg
This" buttons that submit via that mechanism, because the button
really increases the number of their stories submitted to Digg, which
gets them more engagement and traffic. And we like it, too!
But it's important to note that the submissions come from the
users. Digg doesn't support submission without that user interaction.

As I said earlier:
That is an issue that we are looking to solve, especially how
duplicate stories are prevented. Submission via the API will not be
going out with the launch of OAuth and writable endpoints.
Not right now.
>... I would like mobile users of my sites to be able to digg articles.
Well, your mobile visitors can digg stories through Digg's mobile
site, but only if the item has already been submitted. Add "m." to
the start of the permalink URL to link to the story on Digg. Example:
http://m.digg.com/health/Can_Humans_Infect_Pets_With_H1N1
Digg users can log in and digg stories there.
You can use the Digg API to find out whether the story has been
submitted. That's how this "Digg This" button example works:
That example uses client-side Javascript, but you can still use that
approach on the server side to support mobile devices without Javascript.
