I'm developing a SaaS application (ex: mysaas.io) that allows users to connect their own custom domains to their accounts. Currently, I can see that Railway supports custom domain configuration through the dashboard interface, which works great for manual setup.

However, I need to automate this process for my users. Specifically, I'm looking for API endpoints that would allow me to:

• Add custom domains programmatically

• Configure DNS records (A, CNAME, etc.) for user domains

• Manage SSL certificate provisioning for custom domains

• Remove/update domain configurations as needed

Is there a DNS management API available, or are there plans to expose these capabilities ? If this functionality exists, could you point me to the relevant documentation?

If API access isn't currently available, I'd be interested to know if this is on your roadmap, as it would be essential for providing a seamless user experience in my application.

Thx
