# ListEventPredictions
<a name="API_ListEventPredictions"></a>

Gets a list of past predictions. The list can be filtered by detector ID, detector version ID, event ID, event type, or by specifying a time period. If filter is not specified, the most recent prediction is returned.

For example, the following filter lists all past predictions for `xyz` event type - `{ "eventType":{ "value": "xyz" }” } ` 

This is a paginated API. If you provide a null `maxResults`, this action will retrieve a maximum of 10 records per page. If you provide a `maxResults`, the value must be between 50 and 100. To get the next page results, provide the `nextToken` from the response as part of your request. A null `nextToken` fetches the records from the beginning.
