Why this exists
Every federal agency publishes excellent public data for exactly one dimension: EPA for water, FEMA for flood, FBI for crime. A homebuyer, renter, or relocation consultant wanting a full picture has to visit ten different portals with ten different schemas.
zipradar federates those sources behind one address-keyed page. Same public data, one interface. Attribution on every row, regulatory refresh cadence honored, no personal data cached.
zipradar started with the top US metro zip codes and expands weekly. The current coverage map shows every live surface with counts; the methodology page documents source + refresh cadence per dataset.
