Acess to vertex Ai models with api key

[Paragoon2]

Hi, Is it possible to use vertex Ai model only with api key?

Hi @Paragoon2, 

Welcome to Google Cloud Community!

While you can use API key for authentication with Google Cloud Service, Vertex AI requires more than just an API key to access and utilize models. You also need proper project set up and authorization. 

In addition, the API key is part of the authentication process, but authorization (what actions you're permitted to do)  is managed through IAM roles and project configuration. You need both a proper project setup and the appropriate IAM permissions for your Vertex AI model to function correctly. 

For more information about  Vertex AI API you can refer to this documentation. 

I hope the above information is helpful.

And what if I wanted to create an iOS application where I would communicate with a Vertex AI model?
