Using a free trial account for AlchemyAPI (Bluemix), the provided API key only works for:
https://gateway-a.watsonplatform.net/calls/url/URLGetRankedNamedEntities.
But I want to use it for:
https://gateway-a.watsonplatform.net/text/TextGetRankedNamedEntities.
Do I need to add another key, or do I have to upgrade to a premium account?
