# Fetch Traces

`GET /traces/`

Fetch multiple traces by known IDs.

Point lookup endpoint. Accepts either repeated query params
(`?trace_id=a&trace_id=b`) or a comma-separated single param
(`?trace_ids=a,b`). Results are deduplicated. Returns `400` when
no IDs are supplied. Use `POST /traces/query` for filter-based
retrieval.

## Query parameters

- `trace_id` string[], nullable
- `trace_ids` string, nullable

## Response `200`

Successful Response

- TracesResponse
  - `count` integer — Total number of matching traces in the window.

    - `spans` object, nullable
    - `trace_id` string, nullable
