  "name": "NextBlock City explorer relay",
  "description": "The explorer relay of NextBlock City. It takes kinds 0, 3, 5, 16, 22, 1111, 9734, 9735, 10002, 24133, 30078 from any key that completes NIP-42 AUTH, and only from the event's own author, except kind 24133. A read needs NIP-42 AUTH too. A rule refusal starts with invalid:, restricted: or blocked:. A capacity or storage refusal starts with error:, and it refuses an event it cannot keep rather than drop it. A copy, or an older version of a replaceable or addressable event, gets OK true with a duplicate: reason. A kind 24133 is relayed live from any authenticated key, once per id, from 120 seconds before to 60 seconds after the relay clock, and it is never stored. It keeps an event for 4032 blocks from the block height it arrived at.",
