# NIP-21

## `nostr:` URI scheme

`draft` `optional` `author:fiatjaf`

This NIP standardizes the usage of a common URI scheme for maximum interoperability and openness in the network.

The scheme is `nostr:`.

The identifiers that come after are expected to be the same as those defined in [NIP-19](https://github.com/nostr-protocol/nips/blob/master/19.md) (except `nsec`).

## Examples

- `nostr:npub1sn0wdenkukak0d9dfczzeacvhkrgz92ak56egt7vdgzn8pv2wfqqhrjdv9`
- `nostr:nprofile1qqsrhuxx8l9ex335q7he0f09aej04zpazpl0ne2cgukyawd24mayt8gpp4mhxue69uhhytnc9e3k7mgpz4mhxue69uhkg6nzv9ejuumpv34kytnrdaksjlyr9p`

Change NIP-21 URL->URI I think the `nostr:...` scheme is not actually a Uniform Resource Locator, because it doesn't tell you where the data is located. For instance if I see the string `nostr:npub1sn0wdenkukak0d9dfczzeacvhkrgz92ak56egt7vdgzn8pv2wfqqhrjdv9` I understand that this identifies a Nostr keypair but I don't know where to find data for that keypair. The scheme does fall under the definition of a Uniform Resource Identifier, or maybe even the stricter class Uniform Resource Name. But nobody talks about URNs, so maybe best to just use the less-specific term "URI" here. 2023-05-01 14:15:06 -04:00			`This NIP standardizes the usage of a common URI scheme for maximum interoperability and openness in the network.`
