Answer 1

Your URL is wrong. You are pointing at the API Explorer, which used to host the swagger page for the url. Your url should be something like:

https://gateway.watsonplatform.net/assistant/api

For usage check the cURL API Documentation for the service - https://cloud.ibm.com/apidocs/assistant-v2

The actual endpoint you use will depend on the region in which you create your Watson Assistant service. You do need to instantiate an instance in order to be able to use it. When you do instantiate an instance you will be given a url endpoint and an API Key to use. For documentation on the process go to https://cloud.ibm.com/docs/services/assistant?topic=assistant-getting-started#getting-started
