It is particularly valuable when you have 2–20 assets to evaluate simultaneously (batch efficiency) and need structured blocker/warning signals, not just generic sentiment or grammar checks. Prefer this over single-item endpoints when running campaign-scale validation across ads, emails, or landing page sections.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-14T12:44:36.137Z","isFirstParty":false}
