// InvokeEndpoint API operation for Amazon SageMaker Runtime.
//
// 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 (http://docs.aws.amazon.com/sagemaker/latest/dg/how-it-works.html).
//
// 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) (http://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html)
// in the Amazon S3 API Reference.
//
// 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.
//
// Returns awserr.Error for service API and SDK errors. Use runtime type assertions
// with awserr.Error's Code and Message methods to get detailed information about
// the error.
//
// See the AWS API reference guide for Amazon SageMaker Runtime's
// API operation InvokeEndpoint for usage and error information.
//
// Returned Error Codes:
//   * ErrCodeInternalFailure "InternalFailure"
//   An internal failure occurred.
//
//   * ErrCodeServiceUnavailable "ServiceUnavailable"
//   The service is unavailable. Try your call again.
//
//   * ErrCodeValidationError "ValidationError"
//   Inspect your request and try again.
//
//   * ErrCodeModelError "ModelError"
//   Model (owned by the customer in the container) returned an error 500.
