GET /api/v1/traces/service_graph

Returns the raw service-graph edges that Service topology aggregates. Each edge counts the calls from a client service to a server service during one minute. The call requires streams.query, or sys.telemetry.read in the system scope. Query parameters

Param	Type	Required	Notes
`from`	integer	Yes	The start of the window, in microseconds since the Unix epoch.
`to`	integer	Yes	The end of the window, in microseconds.
`service`	string	No	Keeps only the edges that have this service as client or as server.

Response

Field	Notes
`edges[].client_service`, `edges[].server_service`	The calling service and the called service.
`edges[].bucket_at_micros`	The start of the one-minute bucket, in microseconds.
`edges[].request_count`, `edges[].error_count`	The calls and the failed calls in the bucket.
`edges[].p50_us`, `edges[].p95_us`, `edges[].p99_us`	Latency percentiles of the bucket, in microseconds. A percentile can be `null`.
`count`	The number of edges returned.

A window without matching edges answers {"edges": [], "count": 0}, and so does a to that precedes from. Errors

Status	Cause
`400`	`from` or `to` is missing or is not an integer. The response is plain text.
`403`	The token lacks `streams.query`.
