# Fetch Testset

`GET /testsets/{testset_id}`

Fetch a testset artifact by ID.

Returns the artifact row only; testcases are stored on revisions and
must be fetched via `/testsets/revisions/retrieve` or
`/testcases/query`.

## Path parameters

- `testset_id` string, uuid, required

## Response `200`

Successful Response

  - `count` integer — 1 if a testset was returned, 0 otherwise.
  - `testset` Testset
    - `folder_id` string, uuid, nullable
    - `flags` TestsetFlags — Placeholder for testset-level flags. This model is intentionally empty but kept as a dedicated type so that: - existing references to `flags: Optional[TestsetFlags]` remain valid, and - structured flags can be added here in the future without breaking the surrounding DTOs.
