Rating attributes are a numeric value from 0 to 5. In the UI, they are presented as a proportion of 5 stars. There are no default rating attributes in Attio, but they can be created by users and in the API. Only single-select rating attributes are permitted.

​
Reading values

Rating attribute values have a value property: 
{
  "active_from": "2023-04-03T15:21:06.447000000Z",
  "active_until": null,
  "created_by_actor": {...},
  "attribute_type": "rating",
  "value": 3
}

​
Writing values

To write rating values, you can either pass an integer directly, or an object with a single key, value. As all rating attributes are single-select, you may pass the value directly or as an array containing a single element. 
{
  "performance": 4
}

​
Filtering

Ratings can be filtered by the operators $eq, $gte, $gt,$lte,$lt. The implicit syntax does an exact equality check: 
{
  "filter": {
    "performance": 4
  }
}
