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

What it does

  • Address validation and standardization โ€” production-grade parser with ZIP+4 append, refreshed monthly
  • Radius search โ€” 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 โ€” accepts US ZIP, ZIP+4, Canadian FSA, full Canadian postal codes, or latitude/longitude inputs
  • Autocomplete/typeahead โ€” cities, counties, metros, states, FSAs, ZIPs
  • Point-to-point distance โ€” between any two postal points
  • Census ACS demographics โ€” 2011โ€“2024, 542 fields per ZIP across income, education, housing, social, and economic profiles
  • Boundary lookups โ€” Census tracts, congressional districts, state legislative areas, school districts โ€” with computed intersection percentages per ZIP

What makes it different

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

Pricing

  • Free โ€” 2,500 lookups/day, no credit card required, no expiry
  • Developer โ€” $49/mo, 100K credits, 300/min
  • Professional โ€” $149/mo, 350K credits, 300/min
  • Business โ€” $499/mo, 1.5M credits, 600/min
  • Credit packs โ€” one-time, from 25K ($19) up to 2M ($799)
