ListPredictors

Returns a list of predictors created using the CreatePredictor operation. For each predictor, this operation returns a summary of its properties, including its Amazon Resource Name (ARN). You can retrieve the complete set of properties by using the ARN with the DescribePredictor operation. You can filter the list using an array of Filter objects.

Request Syntax

{ "Filters": [ { "Condition": "string", "Key": "string", "Value": "string" } ], "MaxResults": number, "NextToken": "string" }

Request Parameters

The request accepts the following data in JSON format.

Filters

An array of filters. For each filter, you provide a condition and a match statement. The condition is either IS or IS_NOT, which specifies whether to include or exclude the predictors that match the statement from the list, respectively. The match statement consists of a key and a value.

Filter properties

  • Condition - The condition to apply. Valid values are IS and IS_NOT. To include the predictors that match the statement, specify IS. To exclude matching predictors, specify IS_NOT.

  • Key - The name of the parameter to filter on. Valid values are DatasetGroupArn and Status.

  • Value - The value to match.

For example, to list all predictors whose status is ACTIVE, you would specify:

"Filters": [ { "Condition": "IS", "Key": "Status", "Value": "ACTIVE" } ]

Type: Array of Filter objects

Required: No

MaxResults

The number of items to return in the response.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 3000.

Required: No

Response Syntax

{ "NextToken": "string", "Predictors": [ { "CreationTime": number, "DatasetGroupArn": "string", "LastModificationTime": number, "Message": "string", "PredictorArn": "string", "PredictorName": "string", "Status": "string" } ] }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

NextToken

If the response is truncated, Amazon Forecast returns this token. To retrieve the next set of results, use the token in the next request.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 3000.

Predictors

An array of objects that summarize each predictor's properties.

Type: Array of PredictorSummary objects

Errors

InvalidInputException

We can't process the request because it includes an invalid value or a value that exceeds the valid range.

HTTP Status Code: 400

InvalidNextTokenException
