# Fetch Trace

`GET /simple/traces/{trace_id}`

Fetch a single "simple" trace by `trace_id`.

Returns the high-level `SimpleTrace` view (origin, kind, channel,
data, references, links) rather than the raw OTel span shape. Use
this for evaluation results, feedback entries, and annotations
created via `POST /simple/traces/`. For the span-level view of the
same trace, call `GET /tracing/traces/{trace_id}`.

## Path parameters

- `trace_id` string, required

## Response `200`
