AFAIU they work through generic HTTP callbacks. Implementing a LN-Address server can create invoices without being on the same server as the node, or it can be behind a reverse proxy to hide it. You can proxy the outbound response but (a) I absolutely refuse to have a TLS client in my lightning node 🤮, (b) some websites block Tor anyway so callbacks may not be as reliable and (c) proxying through Tor is a bunch more work than just serving being a reverse proxy.
Generally the zap design is horrendous and only makes sense for custodial wallets that already run a bunch of HTTP infra. Luckily there’s a better way (just literally do a BOLT 12 payment and have the payer post the payment proof as a nostr event, rather than making the payee’s lightning node somehow nostr-aware), but need movement there.
