Making a Prediction Using a Model via REST API

Overview

DescriptionMake a prediction using a model.
Resource Path

/api/models/predict?percentile={percentileValue}

HTTP MethodPOST
Request/Response Formatapplication/json
Parameter description
Parameter
Description
{skipDecoding}If this property is set to true, the predicted value is not decoded. This is an optional parameter.
{percentileValue}The percentile value for the prediction. This should be a double value between 0-100. It is required to specify a percentile value when the ML model uses an algorithm of the Anomaly Detection type. This property is optional for other algorithm types. For more information about algorithms of the Anomaly Detection type, see Machine Learner Algorithms.

If you are using a deep learning model to make predictions without H2O runtime, see Using Deep Learning Models without H2O Runtime.
