API REFERENCE

Tracks

On this page

GET/api/research/tracks

Read available artist catalog entries under tracks. Entries can include remixes and features; completeness and fields vary. This endpoint accepts an artist identifier without catalog pagination or filtering controls.

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.

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.
