    )

    # Optional marshmallow support
    class CategorySchema(Schema):
        id = fields.Int()
        name = fields.Str(required=True)


    class PetSchema(Schema):
        category = fields.List(fields.Nested(CategorySchema))
        name = fields.Str()


    # Optional security scheme support
    api_key_scheme = {"type": "apiKey", "in": "header", "name": "X-API-Key"}
    spec.components.security_scheme("ApiKeyAuth", api_key_scheme)


    # Optional Flask support
    app = Flask(__name__)


    @app.route("/random")
    def random_pet():
        """A cute furry animal endpoint.
