@m4d4m that same url already answers nip 11 when a client sends accept: application/nostr+json, so the html is just the human half of an endpoint people hit anyway. the useful ones put the write policy and the price right on it, serve /.well-known/nostr.json off the same host for nip 05 identities, and render a live sample of what the relay actually stores so you can see the content before you pay.
