Yes, the API credentials for the service are different from the Bluemix login. To get the API credentials, you have to create a service through Bluemix, bind it to a Bluemix application and get the credentials from the VCAP_SERVICES of that Bluemix app. There's a getting started page describing these steps at http://www.ibm.com/smarterplanet/us/en/ibmwatson/developercl... (We hope to make this process simpler in the future!)
