New Google Knowledge Graph Search API introduces two editions, Basic and Advanced. For more information, see Basic and Advanced editions.
To support security and compliance requirements, move to a new prediction endpoint. If planning to use the Basic edition, use a new access token or a service account for this API and replace your endpoint URL as shown here:
Cloud Knowledge Graph MID becomes the primary MID (identifier) for the entity. You can still find the Google Knowledge Graph MID in the identifier section for backward compatibility. For more information, see Understand Machine ID (MID).
