### Filters
Filters allow you to narrow down your data to specific criteria. The filter system uses a logical structure:

```json
{
"filter": {
  "AND": [
    {
      "attribute": "domain",
      "comparator": "=",
      "values": [
        {"value": "example.com"}
      ]
    },
    {
      "attribute": "tag",
      "comparator": "=",
      "values": [
        {"value": "newsletter"}
      ]
    }
  ]
}
}
```
**Note:** Filters only support the "AND" operator. "OR" is not supported.  In the example above, only data where the sending domain equals `example.com` and the tag equals `newsletter` will be returned.
**Filter Components:**
- **attribute**: The field to filter on (domain, tag, subaccount)
- **comparator**: The comparison operator (=, !=, contains, not contains)
- **values**: Array of values to match against
