> **v1 is superseded.** v1 was superseded by [v2](/docs/v2/rest-api/operations/listscoringrulesv2) on 2026-08-26\. A sunset date has not been announced yet; v1 will be deprecated as a whole before removal. Migrate with the [v2 migration guide](/docs/migration).

The scoring rules in force for a workspace, or for a project inside it. Each rule is a studio’s own standard that generated assets are judged against, scored 0-100.

Rules are authored in the app under workspace or project settings; this API reads them so a caller can pick which to score against and interpret the scores that come back — the same number means different things under different rules.
