Obtain a Blogger's blog ID from its friendly URL without screen scraping

I'm using the Blogger API for PHP. I want to obtain the blog ID from just the site's name.

For example, http://sleeptalkinman.blogspot.com/ has a blog ID of 3117168333067506122. This is possible as the blog ID appears in the source, but screen scraping isn't a good idea!

Is it possible to obtain it through the API instead of scraping it from the HTML?
