Sure, here are some examples of how to use the Ory Keto SDK in Go and Python. For Go, you can install the gRPC API and REST API with the following commands:

bash go get <http://github.com/ory/keto/proto|github.com/ory/keto/proto>   go get <http://github.com/ory/keto-client-go|github.com/ory/keto-client-go>

Then, you can create minimal permission rules with the following code:

javascript import { Namespace, SubjectSet, Context } from "@ory/keto-namespace-types"      class User implements Namespace { }      class Blog implements Namespace {    related: {    viewers: User[]    }       permits = {    view: (ctx: Context): boolean =>    this.related.viewers.includes(ctx.subject)    }   }

For Python, you can install the Ory Python SDK with the following commands:

bash pip install git+<https://github.com/ory/sdk.git>   python setup.py install --user

Then, you can import the package with the following code:

python import ory_client
