Do I understand correctly that this is an HTTP API with search capabilities and not nostr native websocket NIP-50 compatible with NIP-01 filters?
🍷nostr.wine now supports NIP-50 Search!
filter.nostr.wine has offered NIP-50 for 6 months now and our main relay was starting to fell left out.
We also offer search via our free web API. Learn more here: https://docs.nostr.wine/api/search
Discussion
We offer both. NIP-50 through nostr.wine and filter.nostr.wine websockets as well as an HTTP API.
