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.
Calls 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.
A customer's model containers must respond to requests within 60 seconds. The model itself can have a maximum processing time of 60 seconds before responding to invocations. If your model is going to take 50-60 seconds of processing time, the SDK socket timeout should be set to be 70 seconds.
Endpoints are scoped to an individual account, and are not public. The URL does not contain the account ID, but Amazon SageMaker determines the account ID from the authentication token that is supplied by the caller.

Creating a Request
data InvokeEndpoint Source #
See: newInvokeEndpoint
smart constructor.
InvokeEndpoint' | |
|
Instances
Create a value of InvokeEndpoint
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:accept:InvokeEndpoint'
, invokeEndpoint_accept
- The desired MIME type of the inference in the response.
$sel:targetModel:InvokeEndpoint'
, invokeEndpoint_targetModel
- The model to request for inference when invoking a multi-model endpoint.
$sel:customAttributes:InvokeEndpoint'
, invokeEndpoint_customAttributes
- Provides additional information about a request for an inference
submitted to a model hosted at an Amazon SageMaker endpoint. The
information is an opaque value that is forwarded verbatim. You could use
this value, for example, to provide an ID that you can use to track a
request or to provide other metadata that a service endpoint was
programmed to process. The value must consist of no more than 1024
visible US-ASCII characters as specified in
Section 3.3.6. Field Value Components
of the Hypertext Transfer Protocol (HTTP/1.1).
The code in your model is responsible for setting or updating any custom
attributes in the response. If your code does not set this value in the
response, an empty value is returned. For example, if a custom attribute
represents the trace ID, your model can prepend the custom attribute
with Trace ID:
in your post-processing function.
This feature is currently supported in the AWS SDKs but not in the Amazon SageMaker Python SDK.
$sel:inferenceId:InvokeEndpoint'
, invokeEndpoint_inferenceId
- If you provide a value, it is added to the captured data when you enable
data capture on the endpoint. For information about data capture, see
Capture Data.
$sel:targetVariant:InvokeEndpoint'
, invokeEndpoint_targetVariant
- Specify the production variant to send the inference request to when
invoking an endpoint that is running two or more variants. Note that
this parameter overrides the default behavior for the endpoint, which is
to distribute the invocation traffic based on the variant weights.
For information about how to use variant targeting to perform a/b testing, see Test models in production
$sel:contentType:InvokeEndpoint'
, invokeEndpoint_contentType
- The MIME type of the input data in the request body.
$sel:targetContainerHostname:InvokeEndpoint'
, invokeEndpoint_targetContainerHostname
- If the endpoint hosts multiple containers and is configured to use
direct invocation, this parameter specifies the host name of the
container to invoke.
$sel:endpointName:InvokeEndpoint'
, invokeEndpoint_endpointName
- The name of the endpoint that you specified when you created the
endpoint using the
CreateEndpoint
API.
$sel:body:InvokeEndpoint'
, invokeEndpoint_body
- Provides input data, in the format specified in the ContentType
request header. Amazon SageMaker passes all of the data in the body to
the model.
For information about the format of the request body, see Common Data Formats-Inference.
