How can I verify the Supabase hostname used by an existing deployment?

I need to verify the actual Supabase hostname used by an existing Next.js deployment on Vercel Hobby, without redeploying or changing configuration.

The support chatbot could not verify it: deployment-specific environment values are redacted, and compiled server bundles exceed its inspection limit.

A source comment identifies the project used to generate database types, but that does not prove the runtime connection. Current project environment settings also do not establish what the older deployment uses.

Is there a supported way to inspect the hostname captured for that exact deployment, or obtain deployment-specific evidence of its outbound Supabase destination?

I only need the hostname, not API keys or other secrets. I can provide the deployment ID privately to Vercel staff if needed.
