Is there a tool/link to test a set of RESTful webservices(Stateless) all together in one place?

I am looking for a one tool/GUI link to test my webserices where i can configure all my RESTFul webservices(Stateless) in one UI and then setup a continous integration/Automation testing of these webservices?

The tool/link should be able to : 1. select any webservice from the list and to be able to handle a custom request and show the response instantly. 2. To be able to configure the end points through GUI 3. to be able to run the automated scripts for the testing.

I did some research and found the tool, Swagger.io but it doesnt have any feature to allow to run automated scripts.

Any inputs/suggestions is appreciated.

Thanks in advance
