Authentication

All API endpoints are authenticated using API Keys. These can either be passed directly to the URL or they can be defined in an environment file. Passing Directly: 
"headers": [
  {
    x-api-key: "YOUR_KEY"
  }
]
Environment Variables: 
export VALENCE_API_KEY= "api_key_here"
export VALENCE_DISCRETE_URL= "https://discrete-api-url" # Optional: custom Discrete audio endpoint
export VALENCE_ASYNCH_URL= "https://asynch-api-url" # Optional: custom Asynch audio endpoint
export VALENCE_LOG_LEVEL= "DEBUG"  # Optional: INFO, DEBUG, ERROR
