CreateEndpoint

Creates a model-specific endpoint for synchronous inference for a previously trained custom model

Request Syntax

{ "ClientRequestToken": "string", "DesiredInferenceUnits": number, "EndpointName": "string", "ModelArn": "string", "Tags": [ { "Key": "string", "Value": "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.

ClientRequestToken

An idempotency token provided by the customer. If this token matches a previous endpoint creation request, Amazon Comprehend will not return a ResourceInUseException.

Type: String

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

Pattern: ^[a-zA-Z0-9-]+$

Required: No

DesiredInferenceUnits

The desired number of inference units to be used by the model using this endpoint. Each inference unit represents of a throughput of 100 characters per second.

Type: Integer

Valid Range: Minimum value of 1.

Required: Yes

EndpointName

This is the descriptive suffix that becomes part of the EndpointArn used for all subsequent requests to this resource.

Type: String

Length Constraints: Maximum length of 40.

Pattern: ^[a-zA-Z0-9](-*[a-zA-Z0-9])*$

Required: Yes

ModelArn

The Amazon Resource Number (ARN) of the model to which the endpoint will be attached.

Type: String

Length Constraints: Maximum length of 256.

Pattern: arn:aws(-[^:]+)?:comprehend:[a-zA-Z0-9-]*:[0-9]{12}:document-classifier/[a-zA-Z0-9](-*[a-zA-Z0-9])*

Required: Yes

Tags

Tags associated with the endpoint being created. A tag is a key-value pair that adds metadata to the endpoint. For example, a tag with "Sales" as the key might be added to an endpoint to indicate its use by the sales department.

Type: Array of Tag objects

Required: No

Response Syntax

{ "EndpointArn": "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.

EndpointArn

The Amazon Resource Number (ARN) of the endpoint being created.

Type: String

Length Constraints: Maximum length of 256.

Pattern: arn:aws(-[^:]+)?:comprehend:[a-zA-Z0-9-]*:[0-9]{12}:document-classifier-endpoint/[a-zA-Z0-9](-*[a-zA-Z0-9])*
