Nostr Event Kinds Reference

A complete, machine-readable registry of every defined Nostr event kind — number, name, the NIP that defines it, and its NIP-01 storage class (regular, replaceable, ephemeral, or addressable). Free CSV/JSON and a public REST API under CC BY 4.0.

Quick answer

A Nostr "event kind" is the integer in an event's "kind" field that tells clients and relays what the event means — kind 1 is a short text note, kind 0 is profile metadata, kind 3 is your follow list, kind 30023 is a long-form article. NIP-01 sorts every kind into four storage classes purely by its number: regular (kept forever), replaceable (only the newest per author+kind survives), ephemeral (never stored), and addressable (newest per author+kind+"d"-tag, reachable by an naddr). This registry maps 174 defined kinds to their name, the NIP that defines them, and their derived class — 75 regular, 32 replaceable, 9 ephemeral, 58 addressable.

The most queryable Nostr event-kinds table on the open web — free CSV/JSON + REST under CC BY 4.0. Always confirm against the nostr-protocol/nips repo before building.
