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)

Lean Domain Search features and specs

  • Extensive Database
    Lean Domain Search offers a large database of possible domain names by combining your keyword with hundreds of other terms, increasing the likelihood of finding an available and relevant domain.
  • Speed
    The service provides instant search results, making it easy and quick to identify available domain names without a long waiting period.

  • Social Media Availability
    It offers a feature that lets users check the availability of their domain names across common social media platforms, streamlining the branding process.

Possible disadvantages of Lean Domain Search

  • Limited Niche Suggestions
    The service might not always provide highly creative or niche-specific domain suggestions, as the combinations are somewhat generic.
  • No Bulk Search
    Lean Domain Search does not support bulk domain searches, which may be a limitation for users looking to assess multiple domains simultaneously.
  • Lacks Comprehensive TLD Support
    While it predominantly focuses on .com domains, it has limited support for other top-level domains (TLDs), which can be restrictive for users looking for non-.com options.
  • Potential Overlap
    The common terms used in combination with keywords can lead to overlap with existing, similar domain names, possibly resulting in less uniqueness.
  • No Built-in Purchase Option
    Lean Domain Search does not have an option to directly purchase domains through their platform, which means users need to navigate to a domain registrar to complete the purchase.

ZIP Code API features and specs

  • Comprehensive ZIP Code Data
    The ZIP Code API from zip-codes.com provides extensive data including ZIP code details, city information, state data, and geographic coordinates, making it a thorough resource for location-based lookups.

    The API supports various types of lookups including ZIP code to city/state, city/state to ZIP code, distance calculations between ZIP codes, and radius searches, offering flexible querying capabilities.
  • 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.
