-  title: Prediction Microservice
-  description: |-
-    This is prediction microservice as part of the Novel Metadata Fabric based on the OpenAPI 3.1 specification. It provides a forecasting functionality for pre-defined metrics such as daily energy consumption metrics on the GLACIATION platform. You can retrieve the most recent history and prediction of energy consumption of the platform.
-    
-    You can find out more about
-    the prediction microservice at [https://github.com/glaciation-heu/IceStream/tree/development/prediction_service](https://github.com/glaciation-heu/IceStream/tree/development/prediction_service).
