Nostr relay communication over HTTP(s) (NoH)
|
|
--------------------------------------------
|

|
|
This NIP describes the basic of communicating to relays over HTTP(S) requests.
|
|
|
|
## Communication between clients and relays
|
|
|
|
Relays may expose NoH endpoints that client could reach. Client may make HTTP requests to each relays endpoint for specified tasks as specified in NIP-11. Relays MAY limit number of requests from specific IP/Client/etc.
|
|
|
|
Relays must ensure that the NoH endpoints **MUST** be served with `Access-Control-Allow-Origin: *` header to ensure it can be validated by pure JS apps running in modern browsers.
|
|
|
|
### From client to relay: getting events and sending event
|
|
|
|
Client could make a request to `req` or `publish` endpoint that were specified in `/.well-known/nostr.json`
|
|
|
|
When fetching events, Client can optionally specify filters directly into the URI search query:
|
|
- `<req>?<filter>`
|
|
|
|
`<filter>` is a querystrings that determines what events will be received in that request. it can have the following attributes:
|
|
|
|
```
|
|
ids=<a list of event ids separated by commas>&
|
|
authors=<a list of lowercase pubkeys separated by commas>&
|
|
kinds=<a list of kinds numbers separated by commas>&
|
|
%23<single-letter (a-zA-Z)>=<a list of tag values separated by commas. for %23e — a list of event ids, for %23p — a list of event pubkeys>&
|
|
since=<an integer unix timestamp in seconds, events must be newer than this to pass>&
|
|
until=<an integer unix timestamp in seconds, events must be older than this to pass>&
|
|
limit=<maximum number of events relays SHOULD return in the initial query>
|
|
```
|
|
|
|
Request URL Examples:
|
|
- `https://my-relay.com/__nostr/req?kinds=0,1&limit=10`
|
|
- `https://my-relay.com/__nostr/req?authors=12345,67890`
|
|
|
|
To send event to relay, Client will need to make POST request to `publish` endpoint with POST body containing the JSON blob of the event.
|
|
|
|
### From relay to client: sending responses and notices
|
|
|
|
Every NoH response is a JSON body that contain the following JSON field:
|
|
|
|
- `results`: Array of relay response. Usually contain events requested by client.
|
|
- `notice`: Human readable error.
|
|
|
|
Relay may also respond with HTTP status code:
|
|
|
|
- `200`: OK / Success
|
|
- `400`: Invalid Request
|
|
- `500`: Relay/Server error
