Amazon SageMaker Runtime

{'CustomAttributes': 'string'}

After you deploy a model into production using Amazon SageMaker hosting services, your client applications use this API to get inferences from the model hosted at the specified endpoint.

For an overview of Amazon SageMaker, see How It Works.

Amazon SageMaker strips all POST headers except those supported by the API. Amazon SageMaker might add additional headers. You should not rely on the behavior of headers outside those enumerated in the request syntax.

Cals to InvokeEndpoint are authenticated by using AWS Signature Version 4. For information, see Authenticating Requests (AWS Signature Version 4) in the Amazon S3 API Reference.

    Accept='string',
    CustomAttributes='string'
)

type EndpointName:

string

param EndpointName:

[REQUIRED]

The name of the endpoint that you specified when you created the endpoint using the CreateEndpoint API.

type Body:
