# Stats

To perform a stats query on the cart resource send a `POST` request to the `/carts/stats` endpoint specifying in the payload the [query keys](#query-keys) and [filter](https://docs.commercelayer.io/metrics-api-reference/resources/carts/filters) parameters like in the generic example below:

```json
{
  "stats": {
    "field": "...",
    "operator": "..."
  },
  "filter": { ... }
}
```

{% hint style="info" %}
Please find more information on how stats queries work [here](https://app.gitbook.com/s/ASSiAvbL4nFnkl8plQy2/getting-started/queries/stats).
{% endhint %}

### Query keys

These are the keys you need to set when performing a stats query:

<table><thead><tr><th>Key</th><th>Type</th><th data-type="checkbox">Required</th><th>Description</th><th>Values</th></tr></thead><tbody><tr><td><strong><code>field</code></strong></td><td>String</td><td>true</td><td>The field you want the metrics or statistics computed on.</td><td>See the <a href="#operators-and-field-values">table below</a> to check the full list of valid values for this key.</td></tr><tr><td><strong><code>operator</code></strong></td><td>String</td><td>false</td><td>The computing operator.</td><td>See the <a href="../breakdown#operators-and-field-values">table below</a> to check the full list of valid operators based on the value you assigned to the <code>field</code> key. Default is <code>sum</code>.</td></tr></tbody></table>

### Operators and `field` values

These are the valid values you can specify for the `field` key of the stats query and the related valid operators, based on that key:

| Value                                     | Operators                                                                                                             |
