Task: Explore knowledge graph search api

Practically useless toolkit. Despite the fact that it is still available, data in it is apparently not updated and it is mostly for backward compatibility. In any case, I couldn't find anything at all that I was looking for. And most importantly - it lacks the actual graph itself. That is, even though it is called the Knowledge Graph, essentially there are no connections between individual entities.

Here is what Chatgpt writes about it:

It still works, but Google has been clearly pushing developers to migrate to the Enterprise Knowledge Graph for several years now. Moreover, Google itself explicitly states that the old API is not suitable as a mission-critical production service.
