Fathom Analytics VS ZIP Code API

API for US ZIP, ZIP+4, and Canadian postal code data. One unified endpoint set covers North America — no separate APIs by country or data type.

What it does

Address validation and standardization — production-grade parser with ZIP+4 append, refreshed monthly
Radius search — centroid haversine and true spatial polygon intersection. Returns ZIPs/FSAs within range, with per-result pct_inside overlap percentage for spatial queries
Unified lookup endpoint — accepts US ZIP, ZIP+4, Canadian FSA, full Canadian postal codes, or latitude/longitude inputs
Autocomplete/typeahead — cities, counties, metros, states, FSAs, ZIPs
Point-to-point distance — between any two postal points
Census ACS demographics — 2011–2024, 542 fields per ZIP across income, education, housing, social, and economic profiles
Boundary lookups — Census tracts, congressional districts, state legislative areas, school districts — with computed intersection percentages per ZIP

What makes it different

Licensed commercial data — not commodity or scraped sources
Canadian postal coverage — most peers in this space are US-only
True spatial radius — not just centroid haversine
14 years of historical ACS depth via API — unusual outside of raw Census downloads
One endpoint for all of North America — no country-detection or input-routing logic to maintain on the client side
