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
