Description: `outputs a NIP-01 Nostr filter. when a relay is not given, will print the filter, otherwise will connect to the given relay and send the filter. Description: `outputs a NIP-01 Nostr filter. when a relay is not given, will print the filter, otherwise will connect to the given relay and send the filter.
example usage (with 'nostcat'): example:
nak req -k 1 -a 3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d | nostcat wss://nos.lol nak req -k 1 -a 3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d wss://nos.lol wss://nostr.mom
standalone:
nak req -k 1 wss://nos.lol`, it can also take a filter from stdin, optionally modify it with flags and send it to specific relays (or just print it).
example:
echo '{"kinds": [1], "#t": ["test"]}' | nak req -l 5 -k 4549 --tag t=spam wss://nostr-pub.wellorder.net
