Models

A model is an instance of a machine learning recipe that is trained using historical data and configurations to solve for a business use case.

Retrieve a list of Models

You can retrieve a list of Model details belonging to all Models by performing a single GET request to /models. By default this list will order itself from oldest created model and limit the results to 25. You may choose to filter results by specifying some query parameters. For a list of available queries, refer to the appendix section on query parameters for asset retrieval .
