CreateRealtimeEndpoint - MachineLearning


Creates a real-time endpoint for the MLModel. The endpoint contains the URI of the MLModel; that is, the location to send real-time prediction requests for the specified MLModel.

Request Syntax

{ "MLModelId": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.


The ID assigned to the MLModel during creation.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: [a-zA-Z0-9_.-]+

Required: Yes

Response Syntax

{ "MLModelId": "string", "RealtimeEndpointInfo": { "CreatedAt": number, "EndpointStatus": "string", "EndpointUrl": "string", "PeakRequestsPerSecond": number } }

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.


A user-supplied ID that uniquely identifies the MLModel. This value should be identical to the value of the MLModelId in the request.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: [a-zA-Z0-9_.-]+


The endpoint information of the MLModel

Type: RealtimeEndpointInfo object


For information about the errors that are common to all actions, see Common Errors.
