XML-RPC is not a wordpress plugin. It's part of the base Wordpress platform.
Which is a good thing, because it means just about every wordpress blog (whether self-hosted or hosted on wordpress.com)
will support it, unless the blog author has explicitly disabled it (which is possible and usually done for security reasons; XML-RPC has poor authentication protection).
There is just one more question, i haven't got a wordpress blog, but a website that has its own domain and wordpress framework installed. Can this and/or json api work on that kind of wordpress website?
Yes, it'll work even for a self-hosted wordpress blog which is behind some domain like "http://www.<my-domain>.com/blog". You can try easily using curl tool to check whether it works for your particular blog; URL is usually "http://<your-wordpress-blog-url>/xmlrpc.php". If it doesn't work, then either XML-RPC has been disabled by blog administrator, or its URL has been changed for security reasons.
Note that it gives only XML responses, not JSON responses.
