If you want a programmatic way to create a Tagxedo, you can do that now.

You can control the following parameters: url, theme, font (only one font allowed), orientation, and shape (only default shapes such as "Dove", "Heart", etc -- hover over the default shapes to see their names).  Font names must be exact, or else nothing will load, and white spaces need to be escaped (e.g. space converts to %20).

For example, if you want to make a Tagxedo about CNN, using the "Duality" font, the "Leah Duncan" theme, "Any" orientation, and the dove shape, just go to the following URL:

http://www.tagxedo.com/app.html?url=www.cnn.com&font=Duality&theme=Leah%20Duncan&shape=Dove&orientation=Any

The API is in very beta form and is subject to change.  The basic API will be free, but more advanced API may require a premium license.

Let me know if you have any feedback.
