How to get a list of the XDCR replications?

I’m trying to get a list of the XDCR replications for a given remote cluster, so I can check whether a bucket has replication set up for ElasticSearch, via HTTP. I thought I’d be able to get that by going to the remote cluster URI returned from GET /pools/default/remoteClusters (http://docs.couchbase.com/couchbase-manual-2.2/#getting-a-destination-cluster-reference), but the URI specified in the uri property of the result always returns a 404. Can anyone help me with this?
