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)

  • AI-powered Suggestions
    The platform utilizes artificial intelligence to generate domain name suggestions, often providing creative and unique options tailored to user input.

Possible disadvantages of DomainWheel

  • Limited Search Depth
    While useful, the AI-powered suggestions may not cover extensive variations and combinations of keywords as deeply as some other paid services.
  • Ads and Promotions
    The free nature of the site means it includes ads and promotions, which can be distracting or annoying for some users.
  • No Direct Registration
    DomainWheel does not offer direct domain registration, requiring users to go through partnered domain registrars, adding an extra step to the process.
  • Limited Language Support
    Although it supports multiple languages, the accuracy and relevance of suggestions may still be somewhat limited for less common languages.
  • Basic Interface
    The user interface is straightforward but lacks advanced features and customizations available in more robust domain search tools.
