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

What it does

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

What makes it different

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

Pricing

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

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.
  • Multiple Lookup Options
    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.
  • Well-Documented Endpoints
    The API provides clear documentation for its various endpoints and parameters, helping developers understand available features and implement them correctly without extensive trial and error.

React Server features and specs

  • Server-side rendering built-in
    React Server provides built-in server-side rendering (SSR) out of the box, which improves initial page load performance and SEO without requiring complex custom setup.
  • Fast page transitions
    React Server supports fast client-side page transitions after the initial server render, giving users a smooth single-page application experience while retaining SSR benefits.
  • Built on React
    Since it is built on top of React, developers already familiar with React can leverage their existing knowledge and the vast React ecosystem of components and libraries.
  • Code splitting and lazy loading
    React Server supports automatic code splitting and lazy loading of components, which helps reduce the initial bundle size and improves page load times for end users.
  • Simplified SSR configuration
    Compared to setting up SSR manually with React, React Server abstracts away much of the complexity involved in server rendering, routing, and hydration, making it easier to get started.

Possible disadvantages of React Server

  • Small community and ecosystem
    React Server has a relatively small community compared to mainstream frameworks like Next.js or Remix, which means fewer tutorials, third-party plugins, and community support resources are available.
  • Limited maintenance and updates
    The project has seen limited active development and maintenance over time, raising concerns about long-term viability, bug fixes, and compatibility with newer versions of React.
  • Sparse documentation
    The documentation for React Server is not as comprehensive or well-maintained as that of more popular alternatives, making it harder for new developers to learn and troubleshoot issues.
  • Fewer features compared to alternatives
    Compared to mature frameworks like Next.js, React Server lacks many modern features such as API routes, built-in image optimization, incremental static regeneration, and a rich plugin ecosystem.
  • Risk of project abandonment
    Given the low activity on the project's repository and the dominance of competing frameworks, there is a risk that the project may become abandoned, leaving adopters without future support or updates.

Analysis of ZIP Code API

Overall verdict

  • ZIP Code API from zip-codes.com is a solid, reliable choice for developers and businesses needing accurate US and Canadian postal code data, offering a straightforward RESTful interface with regularly updated databases.

Why this product is good

  • Provides accurate and frequently updated ZIP code, city, state, and geographic data
  • Offers a simple RESTful API that is easy to integrate into web and mobile applications
  • Supports features like ZIP code lookup, radius search, and distance calculations
  • Includes both US ZIP codes and Canadian postal codes for broader coverage
  • Backed by an established data provider with a long track record in postal data

Recommended for

  • Developers building address validation or autofill features
  • E-commerce platforms needing shipping and location-based calculations
  • Businesses performing geographic or radius-based store locators
  • Applications requiring reliable US and Canadian postal data
  • Marketing and logistics teams that need regional or demographic targeting

Analysis of React Server

Overall verdict

  • React Server (react-server.io) is a specialized framework for building server-rendered React applications with a focus on performance and simplified architecture, but I don't have verified, up-to-date information confirming its current status, adoption, or quality compared to alternatives like Next.js or Remix. I'd recommend researching current reviews and documentation directly before making a decision.

Why this product is good

  • Claims to offer server-side rendering capabilities for React applications
  • May provide an alternative approach to SSR compared to more established frameworks
  • Specific technical merits would depend on your project requirements and current documentation

Recommended for

  • Developers researching alternative SSR solutions for React
  • Teams willing to evaluate niche or less mainstream frameworks
  • Projects where established frameworks like Next.js don't fit specific architectural needs
  • Users who should verify current features, community support, and maintenance status before adopting
