title: Jaeger Query Metrics API
description: The Jaeger Query API provides HTTP endpoints for retrieving trace data, service information, operations, and dependency graphs from the Jaeger distributed tracing backend. This API is exposed by the jaeger-query component and is used by the Jaeger UI and other clients to search and retrieve distributed traces collected across microservices.
