List label sets
Grades (labels) API
List label sets
List the workspace's golden sets — named collections of human-graded requests with their measured label quality (inter-rater kappa) — use it to see which sets exist, which are frozen, and which judges calibrate on them.
Returns a bare JSON array, not a { object: 'list' } envelope. kappa is null until the set is frozen, and stays null after freezing when no blind re-grades by a second rater exist inside the set.
