From what I have gathered their main differentiator is taking the approach of assigning each discrete data point its own "entity" definition that is independent but can be extended for each data provider.

So since its all represented by entities, you could treat them like any other vectorised data in your vector data store and use vector search.

It's a nice technique, but probably tricky if they ever venture into encapsulating endpoints in realtime for rapidly changing b2c applications (ratelimits/cronjob latency)
