For starters we have a pretty rudimentary read API with a couple of flavours on the go. We'll add more as time permits and are working on a write API as well.
Any and all ideas welcome for isitbirthday.com. Please contact Gareth at gareth@morethanseven.net.

http://isitbirthday.com/hcard:{url}
For example:
http://isitbirthday.com/hcard:ben-ward.co.uk/about
As suggested by Ben Ward here is a microformats based parser. Point it at a page with an hcard containing the bday property and you'll know straight away whether it's their birthday! Makes use of Glenn Jones's ufXtract microformats parser.
