NIPs registry — kind table and message types

Vendored verbatim from https://github.com/nostr-protocol/nips/blob/master/README.md at the time of 2026-09-21T14:26:31+02:00. Refresh with the snippet in docs/README.md. Upstream dropped its 'Standardized Tags' table; the common-tag list now lives in docs/kind-cheatsheet.md §4.

Event Kinds

This table is not exhaustive. For a machine-readable registry of all known event kinds prefer https://github.com/nostr-protocol/registry-of-kinds (or alternative registries following the same YAML schema).
