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)

Glassdoor Reviews

    Helpful Company Insights โ€” But Reviews Can Be Mixed

    I use Glassdoor mostly to check out companies before applying or interviewing, and itโ€™s helpful to see real peopleโ€™s experiences with culture, pay, interviews, and management. Being able to compare salaries across roles and locations adds valuable context when negotiating or choosing between offers.

    That said, the quality of reviews varies a lot โ€” some are detailed and insightful, while others feel vague or possibly biased. A few companies barely have enough reviews to make a solid judgment, which limits usefulness. And if your priority is finding the biggest, freshest list of jobs, other sites like Indeed or LinkedIn usually have more options.

    Overall, Glassdoor is useful for researching employers and compensation, but itโ€™s not always the most reliable standalone job platform

    ๐Ÿ‘ Pros:    Free access to most content without needing a subscription.
    ๐Ÿ‘Ž Cons:    Some reviews feel subjective, outdated, or inconsistent.
