# ExperimentResponseType

***

# Type Alias: ExperimentResponseType

```ts theme={null}
type ExperimentResponseType = object;
```

Defined in: [src/types/new-api.types.ts](https://github.com/rungalileo/galileo-js/blob/main/src/types/new-api.types.ts)

ExperimentResponse

## Properties

### ~~aggregateFeedback?~~

```ts theme={null}
optional aggregateFeedback: object;
```

Defined in: [src/types/new-api.types.ts](https://github.com/rungalileo/galileo-js/blob/main/src/types/new-api.types.ts)

Aggregate Feedback

Aggregate feedback information related to the experiment (traces only)

#### Index Signature

```ts theme={null}
[key: string]: FeedbackAggregate
```

#### Deprecated

***

### ~~aggregateMetrics?~~

```ts theme={null}
optional aggregateMetrics: object;
```

Defined in: [src/types/new-api.types.ts](https://github.com/rungalileo/galileo-js/blob/main/src/types/new-api.types.ts)

Aggregate Metrics

#### Index Signature

```ts theme={null}
[key: string]: unknown
```

#### Deprecated

Use `metricAggregates` instead, which returns full statistical aggregates
(avg, min, max, p50, p90, p95, p99) keyed by scorer UUID for scorer-backed metrics,
or raw string for system metrics (e.g. 'cost', 'duration\_ns').

### getMetricAggregate()?

```ts theme={null}
optional getMetricAggregate: (metric: string) => Promise<MetricAggregates | undefined>;
```

Defined in: [src/types/new-api.types.ts](https://github.com/rungalileo/galileo-js/blob/main/src/types/new-api.types.ts)

Look up aggregate statistics for a metric by any identifier.
Populated by the SDK via `_enrichExperimentResponse`.

Accepts (in priority order):

1. Scorer UUID string — direct lookup in `metricAggregates`
2. GalileoMetrics value / human-readable label (e.g. "Correctness")
3. Legacy metric\_key\_alias (e.g. "correctness") — fallback after label miss

#### Parameters

##### metric

`string`

#### Returns

`Promise`\<`MetricAggregates` | `undefined`>
