Introduction

Hey everyone, Josh here with more exciting news from the Realie—this time, we’re talking all about the newly minted Realie Property Data API! Before we dive in, let me share a bit about why we built it. As software engineers, my co-founder and I were searching for high-quality property data at a reasonable price for our own projects. What did we find? Mostly high-cost options or questionable data quality. On top of that, the user interfaces felt stuck in the early 2000s—clunky, slow, and anything but intuitive.

That’s when we realized: if nobody else is going to build a fast, modern platform with reliable data at a lower cost, why not just do it ourselves? After months of late-night coding and refining, we’re proud to say we’ve got a solution we genuinely love using—one that’s both developer-friendly and packed with accurate, up-to-date property information.

So, why another real estate API? We’ve poured our engineering expertise into making Realie’s data comprehensive, accurate, and lightning-fast—all accessible through our serverless infrastructure. Whether you’re a real estate professional, investor, or a tech startup in proptech, our API supplies the critical information you need to navigate the market with confidence. Think property characteristics, ownership records, valuation estimates, and sale history—you name it. And just like our public API launch, you can expect the same snappy response times, automatic scaling, and cost-efficiency.

What You Get with the Realie Property Data API

We built the Realie Property Data API with a single aim: to help you make better, data-driven decisions. Here’s a quick look at some of our core features:

  1. Address & Location Data

    • Accurate street addresses, ZIP codes, and geospatial coordinates—ideal for pinpointing areas of interest or conducting neighborhood-level analysis.

  2. Building & Lot Details

    • Instantly access square footage, bed/bath counts, and lot sizes—giving you the context to quickly determine a property’s value or potential ROI.

  3. Ownership & Tax History

    • Stay informed on current and historical ownership details and property tax assessments, helping you better gauge long-term trends and financial risk.

  4. Valuation Estimates

    • Automated Valuation Models (AVMs) for quick property worth estimates—perfect for professionals who need up-to-date market insights (Limited states rolling out January 2025).

  5. Sale & Listing Records

    • Tap into previous sale dates, prices, and local market fluctuations, so you can understand price trends and competitive property landscapes.

Built on a Serverless Backbone

Our Property Data API rides on the same serverless architecture we introduced in our initial public API release. Here’s why that matters:

  • Automatic Scaling

    • Sudden traffic spikes? No problem. Our backend automatically provisions more compute resources to keep things running smoothly.

  • Low Latency

    • With optimized databases handling complex queries, average response times remain in the 100–200ms range.

  • Minimal Cold Starts

    • Through careful infrastructure tuning, we’ve cut cold start times down significantly, delivering consistent performance for all your requests.
