For each rule, the response returns the number of validations that evaluated it, its detection rate, and the mean end-to-end latency of the validations it matched. Set the window with `period` (7d, 30d or 90d, default 30d), or with `start_date` and `end_date` (at most 90 days). ## OpenAPI ````yaml /pt/openapi/v3-current/tracer.yaml get /v1/dashboard/top-rules openapi: 3.1.0 info: title: Midaz Tracer API description: >- Reference for Midaz Tracer transaction validation, fraud rules, spending limits, reservations, and audit events. version: 4.0.0 servers: - url: https://tracer.sandbox.lerian.net security: [] tags: - name: Validations API - name: Rules API - name: Limits API - name: Reservations API - name: Audit Events API - name: Dashboards API paths: /v1/dashboard/top-rules: get: tags: - Dashboards API summary: Get the busiest rules in the window description: >- Use this endpoint to get up to ten rules, ordered by how often they matched in the window.
