Search by query language

Search for artists, albums, tracks by a smart playlist query expression (see README_SMARTPL.md for the expression syntax).

Endpoint

GET /api/search

Query parameters

Parameter	Value
expression	The smart playlist query expression
type	Comma separated list of the result types (artist, album, track
offset	(Optional) Offset of the first item to return for each type
limit	(Optional) Maximum number of items to return for each type

Response

Key	Type	Value
tracks	object	paging object containing track objects that matches the query
artists	object	paging object containing artist objects that matches the query
albums	object	paging object containing album objects that matches the query

Example

Search for music tracks ordered descending by the time added to the library and limit result to 2 items:

curl -X GET "http://localhost:3689/api/search?type=tracks&expression=media_kind+is+music+order+by+time_added+desc&offset=0&limit=2"

Server info

Method	Endpoint	Description
GET	/api/config	Get configuration information

Config

Endpoint

GET /api/config

Response

Key	Type	Value
version	string	forked-daapd server version
websocket_port	integer	Port number for the websocket (or 0 if websocket is disabled)
buildoptions	array	Array of strings indicating which features are supported by the forked-daapd server

Example

curl -X GET "http://localhost:3689/api/config"

{
  "websocket_port": 3688,
  "version": "25.0",
  "buildoptions": [
    "ffmpeg",

    "Spotify",
    "LastFM",
    "MPD",
    "Device verification",
    "Websockets",
    "ALSA"
  ]
}

Push notifications

If forked-daapd was built with websocket support, forked-daapd exposes a websocket at localhost:3688 to inform clients of changes (e. g. player state or library updates). The port depends on the forked-daapd configuration and can be read using the /api/config endpoint.

After connecting to the websocket, the client should send a message containing the event types it is interested in. After that forked-daapd will send a message each time one of the events occurred.

Message

Key	Type	Value
notify	array	Array of event types

Event types

Type	Description
update	Library update started or finished
outputs	An output was enabled or disabled
player	Player state changes
options	Playback option changes (shuffle, repeat, consume mode)
volume	Volume changes
queue	Queue changes

Example

curl --include \
     --no-buffer \
     --header "Connection: Upgrade" \
     --header "Upgrade: websocket" \
     --header "Host: localhost:3688" \
     --header "Origin: http://localhost:3688" \
     --header "Sec-WebSocket-Key: SGVsbG8sIHdvcmxkIQ==" \
     --header "Sec-WebSocket-Version: 13" \
     --header "Sec-WebSocket-Protocol: notify" \
     http://localhost:3688/ \
     --data "{ \"notify\": [ \"player\" ] }"

{
