I'm sorry, but based on the provided extracts, there isn't a direct way to fetch a verification code via the admin API. The verification flow is initiated via the frontend API and the code is sent to the user's email address. However, you can customize the email templates used for verification flows to match the look and feel of your solution. More details can be found in the [custom email template documentation](https://www.ory.sh/docs/kratos/emails-sms/custom-email-templates). If you're using a custom domain, it's recommended to configure a custom SMTP server that matches at least the root domain of your custom domain to prevent emails from being marked as spam. More details can be found [here](https://www.ory.sh/docs/kratos/emails-sms/sending-emails-smtp#send-emails-using-your-smtp-server). Please refer to the [Ory documentation](https://www.ory.sh/docs) for more detailed information.
