You can choose from:

Dataset Diff & Change Detector API in Python

Dataset Diff & Change Detector API in JavaScript

Dataset Diff & Change Detector API through CLI

Dataset Diff & Change Detector OpenAPI definition

You can start Dataset Diff & Change Detector with the Apify API by sending an HTTP POST request to the Run Actorendpoint. An Actor’s input and its content type can be passed as a payload of the POST request, and additional options can be specified using URL query parameters. The Dataset Diff & Change Detector is identified within the API by its ID, which is the creator’s username and the name of the Actor.

When the Dataset Diff & Change Detector run finishes you can list the data from its default dataset(storage) via the API or you can preview the data directly on Apify Console.
