SearchPlay

A play as returned by POST /station. Identical to Play except that station is always present and is always the complete Station object rather than the minimal one.

This play should be considered invalid if a start call is made against another play before starting playback of this song.

idstringrequired

The play id. Numeric, but always serialized as a string. Every subsequent call about this play (start, elapse, complete, skip, invalidate, like, dislike, unlike) is addressed by this id.

Example: 1122334455

audio_file objectrequired

A single playable, transcoded audio file plus its music metadata. Several properties are emitted only when they apply, so their absence is meaningful — see the individual descriptions.

idstringrequired

The Feed.fm audio file id. Numeric, but always serialized as a string.

Example: 9876543

duration_in_secondsintegerrequired

Playback length of the file, in whole seconds.

Example: 213

codecstringrequired

The codec of the delivered file, e.g. mp3 or aac. Selected from the formats the caller asked for.

Example: mp3

urluri

The URL to stream or download. This may be a CloudFront-signed URL that expires roughly 20 minutes after it was issued, so it should be used promptly and never cached long-term. Absent when the play was created without a resolvable URL. If this URL is unplayable because it has expired (it has an Expires query parameter that is a unix epoch timestamp, and it is in the past), then a new POST /play request should be made to generate a new, valid, URL rather than a call to POST /play/{play_id}/invalidate.

Signed URLs include app_id (the authenticated application's ID), client_id (the resolved client's UUID), and, when available, audio_file_id and play_id in the query string. These IDs are covered by the CloudFront signature. Use the complete URL as returned: changing any ID invalidates the URL. These URLs are not bound to an IP address; their 20-minute expiry still applies.

bitrateinteger

Delivered bitrate in kbps. Emitted only when the underlying play has a known bitrate.

Example: 128

track objectrequired

The individual song an audio file renders.

idstringrequired

The Feed.fm track id. Numeric, but always serialized as a string.

Example: 1234567

titlestringrequired

The song title.

Example: Real Live Flesh

release objectrequired

The album the track was released on. Named release throughout the API; there is no album key.

idstringrequired

The Feed.fm release id. Numeric, but always serialized as a string.

Example: 89012

titlestringrequired

The album title.

Example: Kissing The Beehive

artist objectrequired

The performing artist for a track.

idstringrequired

The Feed.fm artist id. Numeric, but always serialized as a string.

Example: 345

namestringrequired

The artist name.

Example: Kissing The Beehive

extra objectrequired

Free-form per-file metadata stored alongside the audio file and passed through verbatim. The keys vary by catalog and by client; treat any key not documented here as optional and unstable. Commonly seen keys include trim_start and trim_end.

property name*any

likedboolean

Present and true when this client has liked the track. The key is omitted entirely when the track is not liked — it is never sent as false, so callers must test for presence rather than for value.

Possible values: [true]

can_seekboolean

Present and true when the licensing for this play permits seeking within the file. Omitted entirely otherwise; never sent as false.

Possible values: [true]

can_cacheboolean

Present and true when the file may be cached locally for offline playback. Omitted entirely otherwise; never sent as false.

Possible values: [true]

previewboolean

Present and true when this play is a preview rather than a reportable play. Omitted entirely otherwise; never sent as false.

Possible values: [true]

replaygain_track_gainnumber

ReplayGain track adjustment in dB, to be applied by the player for consistent loudness. Emitted only when a non-zero value is known.

Example: -6.5

start_atnumber

Offset in seconds the player should start at, rather than the beginning of the file. Emitted only when non-zero.

Example: 30

station objectrequired

A full station. The optional properties are each emitted only under the conditions described below, so their absence carries meaning.

idstringrequired

The station id. Numeric, but always serialized as a string. This value changes with the 'placement id', and so should not be persisted - use the uuid property instead.

Example: 727

namestringrequired

The station's display name.

Example: Pop Rock

on_demandintegerrequired

Whether the station is an on-demand station: 1 for yes, 0 for no.

Possible values: [0, 1]

pre_gainnumbernullablerequired

Station-level gain adjustment in dB, to be applied before playback. null when the station has no adjustment configured.

options objectrequired

Free-form, customer-configured options attached to a station. Contents vary per customer; unknown keys should be passed through rather than rejected.

crossfade_secondsnumber

Crossfade duration for the station, in seconds.

property name*any

Free-form, customer-configured options attached to a station. Contents vary per customer; unknown keys should be passed through rather than rejected.

uuidstringrequired

The station's stable external identifier. Unlike id, it does not change over time.

Example: FgT1_Yzvr_e05ANk2uCYdZi

crossfade_secondsnumbernullablerequired

The station's own crossfade duration in seconds. null when unset. This may differ from the customer-configured options.crossfade_seconds; the two can disagree.

single_playbooleanrequired

true when the station is a single-play station — one track, not a continuous stream.

last_updateddate-timerequired

When the station's contents last changed. Clients use this to decide whether a cached offline copy is stale.

last_play_startdate-time

When this client last started a play on this station. Emitted only when such a play exists, so it is absent for new clients and for stations the client has never played.

expire_datedate-time

When a downloaded offline copy of this station should be considered expired — three weeks from the moment of the response. Emitted only for entries in offline_stations on the session response; it never appears on streaming stations, nor on the station-list routes even when those are listing offline stations.

country_inclusion_modestring

How the countries list should be read: include means the station is available only in those countries, exclude means it is available everywhere but those.

Example: include

countriesstring[]

Two-letter ISO 3166-1 alpha-2 country codes the country_inclusion_mode applies to. Emitted only when country_inclusion_mode is exactly include or exclude, and never null in that case — when the property is present it always carries the list. Absent for any other mode.
