# Stats

> Aggregate cost and reliability metrics for dashboards.

## Aggregate stats

```text theme={null}
GET /api/v1/stats/
```

Optional query:

* `days=<int>`: look back N days

Returns totals such as total runs/actions/cost and average cost/duration per action.

## Daily stats

```text theme={null}
GET /api/v1/stats/daily
```

Returns cost and run counts grouped by day (last 30 days).

## Cost-estimate accuracy

```text theme={null}
GET /api/v1/stats/estimation-accuracy
```

Compares the SDK-supplied `cost_usd` estimate against the actual cost recorded by LLM provider instrumentation, action by action. Returns aggregate skew (mean, p50, p95), the worst-offender actions, and per-action histograms. Useful for tuning your `cost_usd` decorator arguments and for surfacing budget drift in the console.
