WHY NOT JUST USE THE FREE CENSUS API?

The Census API is free.
Connecting the rest is the work.

Use the source directly when it meets your needs. GeoAmCan brings public data from 33 agencies into a common API and geographic framework—so you can spend more time investigating places.

One integration. 33 agencies.

Discover Census, BLS, HUD, Statistics Canada and more through a shared catalog and documented API, with source context retained.

The US and Canada, together.

A shared geographic analysis framework for both countries. Native definitions, release periods and currencies stay explicit.

Data your AI can work with.

Our MCP server gives authorized AI clients dataset discovery and geographic tools. The Librarian explains what to use.
