Ask HN: DNS service with an api

What's a good DNS hosting solution that has a good, straightforward api. (I find route53 to be an api headache)

I use http://www.rackspace.com/cloud/dns/ Free RESTful API with language bindings.

Api docs: http://docs.rackspace.com/cdns/api/v1.0/cdns-devguide/conten...

Python examples: https://github.com/rackspace/pyrax/tree/master/samples/cloud...
