is nak a nostr cli tool? If so, please do link it. noscl is very limited and I have been trying to find a tool to just specify a filter and search relays for them - i.e. to determine of a kind number has been used or not, or just to grab the raw data of an event by filters rather than IDs (i.e. my own kind 0).
