Thank you for reivew @ruromero, I have updated according to your comments. The license update is here #202

Are the V5 endpoints deployed ? the endpoints remain as per openapi.yaml But I see this response:

 Output structure: {
  "providers": {}
}

and error output is empty - only contains empty providers for integration tests.
