omgwtfnzbs is on the wrong adress?

I find it wierd that CP is using rss site when they have a seperate api site for api calls.
here is their info about api from their website (using the api.omgwtfnzbs.org adress)

To access the API you will need an API Key.

You should use the HTTPS GET method for sending queries to the sever. POST method is not supported.
ANY Abuse of the API will result in an API ban, and or further restrictions.
We reserve the right to ban any user(s), IP(s) etc without notice, if in breach of the above.
