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)

Possible disadvantages of Tailwind UI

  • Cost
    Tailwind UI is a paid product, which can be a barrier for small projects or individual developers who are operating on a limited budget.
  • Learning Curve
    While Tailwind UI components are easy to use, the underlying Tailwind CSS framework can have a learning curve for those unfamiliar with utility-first CSS approaches.
  • Overhead
    Incorporating a large number of components can increase the initial bundle size, which may affect the performance unless optimized appropriately.
  • Dependency on Tailwind CSS
    Tailwind UI components are tightly coupled with Tailwind CSS, which means switching to or migrating from another CSS framework may require substantial effort.
  • Not Always Unique
    Using pre-built components might result in less unique designs, as other developers and projects using Tailwind UI can have similar looks and feels.
  • Limited Scope
    The pre-designed components cover a wide range but may not fulfill every niche use case, requiring additional custom development or design.

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.

  • Getting Tailwind CSS Running in React and Next.js (Without the Headaches)
    Tailwind UI is a commercial component library, but even the free examples teach you solid patterns for responsive design and component architecture. I learned a lot just by reading through their example code. - Source: dev.to / 10 months ago
  • Ask HN: Link to interactively learn UI/Typography design
    Studying existing component systems is a great starting point. You have to imitate and respect the systems that already exist before you can innovate on new things from scratch. I'd recommend starting by reading, building with, and imitating the most well-known frameworks for some personal projects. You can also find some good Figma projects to get started with on each of these. https://tailwindui.com/. - Source: Hacker News / almost 2 years ago

  • Ant Design โ€“ the second most popular React UI framework
    There's https://tailwindui.com/?ref=top, from the Tailwind CSS people. They come with a "HTML" mode, which I think means no JS. But if you need interactivity, on the web it has to be JS, because that's the only thing that can manipulate the DOM. The alternative would be something like a server-updated Canvas where the UI is done outside of the DOM and not in the client, but even that would need some JS shims just... - Source: Hacker News / about 2 years ago
