1. Securing Access to AI APIs with Auth0 Client Grants


    To secure access to AI APIs using Auth0, you will define the entities required to set up the authorization mechanism. In this context, you will create a Client and a ClientGrant with Pulumi using the Auth0 provider.

    Here's what will happen:

    1. Client: This represents the application that will be making requests to your AI API. In Auth0 terms, it is often referred to as an application or machine-to-machine application.

    2. ClientGrant: This defines the scopes and permissions that your Client has on your API (represented as an Audience in Auth0). It enables your Client to obtain an access token, with the appropriate permissions, that can be used to make authenticated requests to your API.

    The Auth0 setup assumes you have an API (also referred to as an Audience in the Auth0 dashboard) already set up in your Auth0 tenant to represent your AI APIs.

    Below is a Python program using Pulumi to set up these Auth0 entities:

    import pulumi import pulumi_auth0 as auth0 # Replace these values with your actual client and API settings. client_name = "My AI Client App" api_identifier = "https://myapi.example.com/" # The identifier of the API you have configured in Auth0 # Create a new Client (application) in Auth0. ai_client = auth0.Client("ai-client", name=client_name, grant_types=["client_credentials"], # client_credentials grant type is used for machine-to-machine communication app_type="non_interactive", # Indicates that the app is a machine-to-machine app ) # Replace 'read:data', 'write:data' with actual permissions (scopes) defined in your Auth0 API. client_grant_scopes = ["read:data", "write:data"] # Create a ClientGrant for the client to access the specified API with the given permissions. ai_client_grant = auth0.ClientGrant("ai-client-grant", client_id=ai_client.client_id, audience=api_identifier, # The Audience is your AI API's unique identifier. scopes=client_grant_scopes, ) # Export the Client ID and Client Grant ID for reference. pulumi.export("client_id", ai_client.client_id) pulumi.export("client_grant_id", ai_client_grant.id)

    In this program:

    • We import the pulumi and pulumi_auth0 modules so we can use Pulumi and the Auth0 provider to manage our Auth0 resources.
    • We define a new Client (ai_client) using the auth0.Client class, specifying its name and grant types. The client_credentials grant is typically used for server-to-server communication.
    • We then create a ClientGrant, which connects our previously defined Client to the API, specifying the allowed scopes using the auth0.ClientGrant class.
    • Lastly, we export the Client ID and Client Grant ID using pulumi.export() to make them available outside of our Pulumi program, for example, for use in CI/CD or logging.

    Once this Pulumi code is deployed, the Client and ClientGrant will be set up in your Auth0 environment, and your application can authenticate itself to Auth0 to receive tokens. These tokens can be sent as an Authorization header to your AI API to authenticate requests.

    To deploy this code, you need to have the Pulumi CLI installed and configure Pulumi to use your Auth0 Domain and Management API Token so it can manage resources in your Auth0 account. Once the CLI is configured, you can run pulumi up from the directory with this code to start the deployment process.
