# Get the AI Security for Apps custom topics of a zone.

GET/zones/{zone\_id}/ai-security/custom-topics

Get the custom topic categories defined for the zone. While AI Security for Apps is enabled, it scores every incoming prompt against these topics and writes the scores to the `cf.llm.prompt.custom_topic_categories` field, keyed by topic label. Topics can be configured while the detection is disabled, but no prompt is scored until you enable it.
