API REFERENCE

Playlist Placements

On this page
GET/api/research/playlists

Read available playlist placements for an artist. status=current selects current scope; status=past selects all-time scope, which can include current placements. limit is an optional raw string with no Recoup default; supported limits and coverage depend on the data connection.

Use your Recoup API key (x-api-key) or supported bearer credential. Successful artist and track research reads cost $0.05 (50,000 micro-dollar credits). Recoup manages the data connections. Coverage and rate limits vary; see Research availability.

Parameters

Query parameters

artiststring

Artist name; Recoup resolves the first provider search match. Required unless id is supplied. Recoup artist UUID resolution is not implemented here.

platformstring · enum

Values: "spotify", "applemusic", "deezer", "amazon", "youtube"

Default: "spotify"

statusstring · enum

current uses current placements; past uses all-time scope total, which may include current placements.

Values: "current", "past"

Default: "current"

limitstring

Optional raw string; no Recoup default. For similar artists, only a positive integer limits the returned list; for playlists it passes through to the provider.

idstring

Research artist ID returned by search or lookup; treat it as an opaque string. Required unless artist is supplied; takes precedence when both are provided. This is not a Recoup artist/account ID.

billingUrlstringrequired

Static link to the Recoup app, where a human can save a card and buy credits. It is a constant, not a freshly minted Stripe Checkout Session, so a credit-gated endpoint that keeps returning 402 creates nothing. To buy credits programmatically, call POST /api/credits/sessions.
