Free: $0, 5k/mo. MIT licensed.
I built Polyhistor because existing location APIs like Google Places can tell you WHERE a place is — but not HOW it feels to be there, or WHEN is the best time to visit.
The idea started from a simple frustration: planning a day out in a new city means juggling 5+ tabs — Google Maps, Yelp, Instagram, Reddit, and random blogs. You never know if a place is packed or peaceful until you're already there.
We spent 6+ months building a location intelligence engine on 3.55M places across 50 US metros. The result: an API that understands the vibe (cozy, romantic, hip), the crowd patterns (peak, quiet, closed), and temporal intelligence — all at 4x faster speeds than other commercial providers and a fraction of the cost ($297/mo vs $22,880/mo).
MIT licensed and free for small teams. Would love your feedback!
