# List a target’s published generations

`GET /v1/benchmark/target/{targetKey}/history`

## Request

- Base URL: `https://api.roark.ai`
- URL: `https://api.roark.ai/v1/benchmark/target/{targetKey}/history`
- Auth: HTTP bearer

Returns every sweep published for a target, newest first, including superseded ones. This is the trend read: it answers "did this model regress?" from Roark’s own published record. Metadata only — pass a row’s `publicationId` to GET /v1/benchmark/target/{targetKey} for that generation’s numbers.

## Path parameters

- `targetKey` string, required

## Query parameters

- `suite` string, required
- `suiteVersion` string
- `limit` integer: Maximum number of records to return (default: 20, max: 100)
- `offset` integer: Pagination offset

## Response `200`
