    description: >-
      Tempo exposes an HTTP API for querying traces, searching spans, discovering
      tag keys and values, and generating metrics from trace data. The API is compatible
      with Jaeger and Zipkin query protocols in addition to the native Tempo protocol.
      Used by Grafana dashboards, the Tempo CLI, and external integrations.

  - name: Tempo TraceQL API
    description: >-
      TraceQL is a query language developed for Grafana Tempo that allows filtering
      and selecting spans within traces. The TraceQL search API endpoint enables
      rich span-level filtering using a pipeline syntax with attribute matchers,
      duration filters, and structural operators.
