Find top artist, track, playlist, and user matches for a query. Returns basic identity and display data in source order, without enriched metrics. A single requested type uses its dedicated provider-ranked result list. Omitted or multiple types use the mixed top results and then filter by the requested types. Fewer items than the limit may be returned, including none. Generated mixes and unsupported entity types are excluded. This endpoint exposes no pagination or total count. Regional context is best effort and may differ when a fallback connection is used. Use playlist search for filtering stored playlist data and keyword search for stored keyword research.
