The API Stack Powering the Next Generation of Real Estate Platforms

A few years ago, I moved to Zaragoza, Spain. A city that I'd never set foot in before. I spend hours on Google Maps manually searching for "gyms near [address]," "restaurants near [address]," "metro stations near [address]" — trying to piece together which neighborhoods were safe, convenient, and actually livable.

I was doing the job that PropTech platforms should be provided.

I picked an apartment that looked good on the real estate platform. Within a year, I moved again. This time, to a neighborhood I'd discovered after being there in person. The stress of moving twice? I wouldn't wish that on anyone.

The users, especially those relocating to unfamiliar cities, are facing this exact problem every day. And every time they leave your platform to research neighborhoods on Google Maps, you've lost them.

The platforms winning right now aren't the ones with the most listings. They're the ones delivering location intelligence at scale that automatically enriches every property with the context users need to make confident decisions.

This is the opportunity. And this is how to build it.

Digital Ecosystem Demand Location Intelligence

According to Fine Magazines, in 2025, real estate platforms function as digital ecosystems, offering AI-driven recommendations, virtual tours, and neighborhood insights all in one place. Users expect to browse listings, explore neighborhoods, and make decisions without leaving the platforms.

But building these ecosystems requires data. Specifically, structured location data that can power recommendations, extract nearby amenities, and provide neighborhood context at scale. That's where a real estate data API stack comes in.

The Property Research Problem No One Talks About

My Zaragoza experience isn't unique. There are millions of users relocating every year to cities they've never visited. They need neighborhood context. And right now, most PropTech platforms can't deliver it.

Here's what most PropTech founders won't admit publicly: their 'neighborhood data' is a patchwork of manual research, outdated datasets, and educated guesses.

"Finding that data fragmentation, inconsistent quality, and high access cost remain major stumbling blocks across UK, USA, China, and India"
- A 2025 report from Warwick Business School

Without a scalable real estate data API solution, the symptoms show up everywhere:

• Listing goes live half-empty. Square footage? Check. Photos? Check. What's within walking distance? "TBD"
• Users bounce. Every time a buyer or renter opens a listing, they need to confirm the location and the nearby area on Google Maps, GreatSchools, or Reddit to fill in the gaps your platform left; you've lost their attention. Worse, you've trained them to see your platform as incomplete. The platform winning today keeps the user experience inside. Surfacing school ratings, transit times, and local amenities without forcing users to research for themselves.
• Your team becomes a bottleneck. Every new market you enter means more manual research. More hours. More inconsistency. Your growth is literally capped by how many browser tabs your team can keep open.
• Address data is a mess. User types "123 Main St", twelve different ways. Your database has duplicates, typos, and listings that don't actually exist. Search becomes unreliable. Trust erodes.

Meanwhile, your competitors, who are the ones raising bigger rounds and signing enterprise deals, have already solved this problem. They've built a real estate data API stack that automates what your team still does manually.

What Winning PropTech Platforms Do Differently

The platforms pulling ahead aren't working harder. They're not hiring armies of researchers. They've built a real estate data API stack that powers automated location intelligence across their entire infrastructure.

Think about what users like me actually needed when apartment hunting:

• Nearby amenities: Grocery stores, gyms, restaurants, and parks within walking distance.
• Public transport access: Tram or metro stations, bus lines, and commute times.
• Neighborhood quality: Is this area lively or dead? Safe or sketchy?
• Verified addresses: Is this listing even real?

Winning platforms answer all of these questions automatically at scale for every listing.

Here's what a property listing enrichment looks like in practice:

Help users find the right location.

When users search for properties, typos and incomplete queries lead to frustration. For example, they type "Av de Goya, 90". With SerpApi's Google Maps Autocomplete API it will show you autocomplete suggestions, reducing errors, guiding them to real places, and returning coordinates which you can use for further enrichment.

What's around this property?

When a listing enters the system, it will automatically be tagged with nearby context:

• Schools (with rating and distance).
• Hospitals, pharmacies, and urgent care facilities.
• Public transit stops and commute times.
• Grocery stores, restaurants, gyms, banks, parks, and more.

With SerpApi's Google Maps API, a single API call returns ratings, reviews, exact addresses, hours, and GPS coordinates for any location.

The image above shows an example result from our playground. You can set the coordinates from the address and send the search query. In this example, the results show the available pharmacies around "Avenida Francisco de Goya, 90" including their details such as opening hours, full address, phone numbers and more.

What's missing here?

Users don't just want to know what's nearby, they also want to know what's not there.

No grocery store within walking distance? That's a dealbreaker for some. Only a few restaurants in the area? The neighborhood might be too quiet for other. No gyms nearvy? Fitness-focus renters will look elsewhere.

With the same Google Maps API, you can send query by category and identify the gaps that matter to users. This will help them to make a better decision before they commit.

What's the distance between the home and ... ?

Users don't just want to know what's nearby; they want to know how long it takes to get there. Commute time to work, walking distance to the public transport, or driving time to the nearest school.

With SerpApi's Google Maps Direction API, you can extract travel times between any two points by car, transit, walking, or cycling.

We return structured direction data including the steps it took for every directions giving users a clear picture of their daily commute. By default, it shows the result for the best travel mode. However, you can cutomize by setting the travel_mode parameters.

Is this a good neighborhood?

This is the question every user asks and the hardest one to answer at scale.

While this topic isn't 100% of the PropTech platform's job to judge, at least you can give users the data to decide for themselves. High-rated coffee shops, busy restaurants, and well-reviewed local services can be a good indicator of a healthy neighborhood.

With SerpApi's Google Maps Reviews API, you can aggregate user reviews and sentiment data from local businesses by extracting ratings, reviews counts,review snippets, images (if it was uploaded) price range for every restaurants and more.

In the example above we can see the details review. Even though the review is in Spanish, SerpApi returns to you both the original language and english translation making it easy to analyze sentiment regardless of location.

The Real Cost of Waiting

Every day your platforms run without automated location intelligence, you're:

• Losing users to competitors with better real estate amenities mapping
• Burning money on manual research that doesn't scale
• Missing opportunities because you can't see market gaps
• Building technical debt with messy address data that will haunt you later
• Watching users bounce to Google Maps, Yelp and etc to do research you should have provided.

The PropTech platforms that will dominate the next decade aren't the ones with the most listings. They're the ones delivering the most context around their listing.

A robust real estate data API stack isn't a feature anymore. It's the foundation of every successful PropTech location intelligence strategy.

Why SerpApi Instead of Google Maps API Directly?

Google's Official Places API provides similar structured data, such as nearby places, reviews, and directions. So why use SerpApi?

Key Differences

Note on Popular Time: If you've ever looked at a business on Google Maps and seen the bar chart showing when it's the busiest, that's "Popular Time" data. It's valuable for PropTech platform (imagine showing users when nearby gyms or coffee shops are crowded). Google's official API does not expose this data. SerpApi returns it through the place_results endpoint requiring a second API call using the place_id from your initial local_results search. While it's an extra step, the data itself is available and structured as a busyness_score per hour for each day of the week.

Note on FieldMask: Google's Places API (New) requires you to specify exactly which fields you want in every request using X-Goog-FieldMask. Different fields fall into different pricing tiers (Essentials, Pro, Enterprise) so requesting reviews costs more than requesting displayName. This adds complexity to both your code and your billing. With SerpApi, you get all available data in one response with predictable pricing.

When Each Makes Sense

Choose Google Maps Platform if:

• You need map visualization (Maps JavaScript API)
• You require official support and SLAs
• You have high volume (250K+ calls) where subscription pricing is cost-effective
• Enterprise requirements mandate official APIs

Choose SerpApi if:

• You want simple, predictable monthly costs
• You need data from multiple sources (Google + Bing + Yelp)
• You want all data returned without managing field masks
• You need Popular Times or other browser-visible data
• You need more flexibility in how you store and use the data

Beyond Google Maps: Multiple Data Sources

SerpApi isn't limited to Google Maps. You can enrich your listings with data from multiple sources through a single API provider:

Why Use Multiple Sources?

• Richer data: Yelp has deeper restaurant and nightlife reviews; Google has broader coverage.
• Redundancy: If one source lacks data for a location, another might have it.
• Different perspectives: Yelp users and Google users rate businesses differently. By combining both it gives a fuller picture.
• Market-specific coverage: Bing Maps may have better data in certain regions.

For example, when building a neighborhood quality score, you could combine:

• Google Maps Reviews: General local business sentiment.
• Yelp Reviews: Detailed restaurant and nightlife ratings.

This gives your users a more complete picture than relying on a single source.
