Try afraid.org, the site looks old, but they offer a very full featured service. It does have a free plan, with I think 5 free domains, they don't have a required update interval, and you can update the IP of a domain with https://[USERNAME]:[PASSWORD]@freedns.afraid.org/nic/update?hostname=[DOMAIN]&myip=[IP]. The API docs are here.
