"WikiGrok prompts a user to confirm metadata information that will be eventually stored in Wikidata". This might serve as an introduction to querying and updating Wikidata for the Data and developer hub.

Looking at the extension's code, the client talks to WikiGrok and all interaction with Wikidata is in PHP code invoking Wikibase methods. This is relevant to other extension authors, but not for external developers wanting to access Wikidata.
