Need some suggestions for testing /.well-known/host-meta

So I have another service that I use (not on activitypub) that I am hosting in a subdomain but generating a handle with my main domain. pretty much like akkoma does.
eg. server on server.domain.com and handle like me@domain.com.

And this service also uses /.well-known/host-meta with an XRD response.

I merged both XRDs and it works for this other server, but I don’t know how I could test it for akkoma before deploying.

Any suggestions how I could test it?
