# Get incomplete evaluations for an experiment

`GET /v1/experiments/{experiment_id}/incomplete-evaluations`

Get experiment runs that have incomplete evaluations.

Returns runs with:
- Missing evaluations (evaluator has not been run)
- Failed evaluations (evaluator ran but has errors)

Args:
    experiment_id: The ID of the experiment
    evaluation_name: List of evaluation names to check (required, at least one)
    cursor: Cursor for pagination
    limit: Maximum number of results to return

Returns:
    Paginated list of runs with incomplete evaluations

## Path parameters

- `experiment_id` string, required

## Query parameters

- `evaluation_name` string[] — Evaluation names to check
- `cursor` string, nullable — Cursor for pagination
- `limit` integer — Maximum number of runs with incomplete evaluations to return

## Response `200`
