Perspective API
Last reviewed by Moderation API
Perspective API is a public toxicity classification service from Google Jigsaw that scores text across attributes such as toxicity, severe toxicity, insult, threat, and identity attack. It is widely used by publishers, forums, and researchers as a baseline for detecting harmful conversational content.
In 2026 Google announced it is winding the service down. Existing keys keep working through the published sunset window, but it is no longer accepting new sign-ups and will not be a long-term option for production workloads. Teams that depend on Perspective scores need to migrate.
