Following we are listing the available endpoints, and provide examples of sample requests. All listed URLs must be pre-pended by "http://hostname:port/curator" where "hostname" and "port" are the fully qualified domain name and port where the Curator web application is deployed. We use "curl" as example client to issue HTTP requests.
