API REFERENCE

Milestones

On this page

GET/api/research/milestones

Read available artist activities under milestones. Coverage varies; an empty result does not prove the artist has no milestones. This endpoint does not guarantee a complete history or scored career timeline.

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.
