Nostr Implementation Possibilities (NIPs) is one of 4 APIs that [Nostr](https://apis.io/providers/nostr/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include NIPs, Event Kinds, Extensions, and Standards.

NIPs are the standards documents that extend Nostr beyond the core protocol. They define event kinds (text notes, reactions, zaps, long-form articles, DMs, calendar events, marketplaces), client behaviors (NIP-05 verified handles, NIP-07 browser signers, NIP-46 remote signers), and relay capabilities (NIP-11 relay information, NIP-42 authentication). Conformance is informal — clients and relays pick the NIPs they support.
