  title: Scanner Ad Hoc Queries Detection Rules API
  version: v1
  description: Scanner is a cloud-native security data platform that indexes logs directly in Amazon S3 for fast full-text search, continuous streaming detections, and programmatic access to security data. This REST API (v1) covers searchable indexes, detection rules, event sinks, lookup tables, ad hoc queries, and account/query-capacity info. Authentication is a Scanner API key presented as an HTTP Bearer token. Most operations are tenant-scoped and require a `tenant_id`. The API base URL is environment-specific and shown in Settings > API Keys inside the Scanner app.
