For a relatively small academic research project, I am trying to use Google Cloud Natural Language API.
From what I understood on the Authentication Overview, it looks like an API key would be the best and simplest approach to authentication, rather than a service account or user account.
Creating the key was easy enough. But now I am stuck on how to actually use it in conjunction with gcloud commands on an Ubuntu VM instance on Google cloud compute engine.
When I try to run the simple example on the Natural Language Quickstart Guide, I get this error:
gcloud ml language analyze-entities --content="Michelangelo Caravaggio, Italian painter, is known for 'The Calling of Saint Matthew'."
ERROR: (gcloud.ml.language.analyze-entities) PERMISSION_DENIED: Request had insufficient authentication scopes.
The documentation and Q&A I've seen related to this error are related to service accounts or user accounts, but I am trying to just use the "simple" API key.
The documentation for Using an API key shows how to do so via REST. But, for now as a "quick" test to see if I have the Natural Language API working, I want to just do a simple test with gcloud on the command line. I looked through the gcloud documentation, but could not find anything about specifying an API key string.
How can I run the above command with gcloud and authenticate with my API key?
If this API key turns out to be more of a hassle, I may consider switching to a service account.
Any help would be greatly appreciated...
