    "description": "The aggregation API allows you to compute aggregated results on events \nlike getting the count of all events in a project or checking what are all the \ndifferent types and subtypes of events in your project, along with \nthe count of events in each of those aggregations. By specifying an additional \nfilter, you can also aggregate only among events matching the specified filter.\n\nThe default behavior, when you do not specify \nthe `aggregate` field in the request body, is to return the count \nof events.\n\nSetting `aggregate` to `uniqueValues` will return all unique values (up to a \nmaximum of 1000) and the count of each in the field specified in \n`fields: []`. Note that, currently, you can only request for unique \nvalues on a single field. Also, in the case of text fields, the values are \naggregated in a case-insensitive manner. For example:\n\n```\n{\n  \"aggregate\": \"uniqueValues\",\n  \"fields\": [ \"type\" ]\n}\n```\n\nwill return all unique 'types' in the events in your project.\n\nSimilarly,\n\n```\n{\n  \"aggregate\": \"uniqueValues\",\n  \"fields\": [ \"dataSetId\" ],\n  \"filter\": {\n    \"subType\": \"subtype_1\"\n  }\n}\n```\nwill return all unique dataSetIds in events of subtype 'subtype_1'\n",
