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)

    Unlike some other platforms, AlgoExpert.io has limited community features, such as forums or discussion boards, where users can interact and collaborate with each other.
  • No Direct Mentorship
    There is no direct access to mentors or instructors for personalized guidance, which may be a drawback for users who prefer more hands-on mentorship.
  • Static Content
    Once a problem set and its explanations are published, they rarely get updated. This might lead to outdated content as new algorithms and coding patterns emerge.

  • Easy Integration
    The API uses standard REST-based HTTP requests and returns data in commonly used formats like JSON and XML, making it straightforward to integrate into most applications and programming languages.
  • Distance and Radius Calculations
    The API includes built-in functionality for calculating distances between ZIP codes and finding ZIP codes within a specified radius, which is valuable for store locators, shipping estimates, and proximity-based features.
  • Well-Documented Endpoints

  1. Chris Grier
    Weak product. Not worth it.

    Their interview questions are pretty basic and the whole product is pretty much useless. Waste of time and money.
