We all know how crucial it is to have our fingers on the pulse of the property market, right? That’s where real estate APIs come in. The best real estate APIs have become essential tools, providing structured access to property listings, valuations, rental analytics, neighborhood insights, and more.
But here’s the thing: APIs aren’t always perfect. Sometimes they fall short on coverage, hit you with tough rate limits, or struggle to keep up with the lightning-fast pace of the market.
This is where scraping tools like ScrapingBee come into play. This API lets you grab data from websites that don’t have official APIs or when the existing ones just aren’t cutting it.
Of course, there are notable alternatives, so I wrote this article to review the best real estate APIs in 2026. I'll look at what makes them shine, where they might stumble, and how a bit of clever scraping can help you create truly stellar real estate applications.
TL;DR: Quick Answer
Real estate APIs can help you build great apps and gather market intelligence without manual effort. With some coding and a simple setup, these tools gather fresh, accurate real estate data in your preferred format.
However, not all of these APIs are the same. Some excel at listing data, others specialize in valuations or rental analytics, and others offer reliable neighborhood and demographic insights. They can also come with limitations. Regional restrictions, rate limits, or incomplete data fields can be common challenges if you don't have the right tool for the job.
If you're looking for a well-rounded solution that covers all bases, ScrapingBee is the number one choice. Of all of the tools I tested, it's the most reliable scraping solution on the market.
Best Real Estate APIs for 2026
Different real estate APIs cater to different needs. Some focus on nationwide property records, others on rental analytics, geospatial data, or school ratings. When choosing an API, consider factors such as reliability, data freshness, breadth of datasets, documentation quality, and whether the API covers global markets or is limited to the US or Europe.
1. ScrapingBee – The Best Real Estate API
ScrapingBee is not a traditional real estate API but a powerful tool for extracting property data from websites that lack official APIs.
The platform's Real estate data API offers headless browser rendering, captcha bypassing, and geo-targeted scraping, making it invaluable for markets where official APIs are limited or restrictive.
Both developers and business analysts often use ScrapingBee to unify listings from multiple sources or supplement official APIs to get a more comprehensive dataset.
2. ATTOM
ATTOM provides a comprehensive nationwide dataset including property records, deed and mortgage data, neighborhood demographics, school information, and Automated Valuation Models (AVMs).
Its strong documentation and extensive data make it a favorite for developers who need deep property insights. However, pricing can be a consideration, and some regions may have less detailed coverage.
3. Zillow
Zillow API has historically been popular but has faced limitations due to restricted access and the shutdown of older endpoints. To scrape Zillow, many developers supplement its official API with scraping techniques and other Zillow scraping APIs to overcome these restrictions and access richer data. While Zillow offers valuable listing and valuation data, its API access policies require careful navigation.
4. Realtor
The Realtor API is known for access challenges and licensing restrictions. Learning how to scrape Realtor requires some technical knowledge and unofficial sources when the official API falls short in coverage or data freshness.
Despite these hurdles, Realtor.com remains a key source for US listings.
5. Redfin
Redfin offers data on property listings, sales, and market trends. While its API access is limited, it provides useful data for certain use cases such as market analysis and property metadata.
If you want to scrape it properly, you'll need a Redfin scraper API to complement Redfin’s official data.
6. Multiple Listing Services (MLS)
MLS data is the backbone of real estate listings in the US, but is fragmented across many regional systems.
Accessing the data can be challenging due to proprietary restrictions and licensing. Official MLS APIs provide authoritative data but often have limited public access. Thus, I recommend getting an MLS scraper.
7. Idealista
Idealista, one of the leading real estate portals in Spain, Italy, and Portugal, offers a Search API that lets developers query live sale and rental listings with filters for location, price, property type, and more.
Access is granted on request and authenticated via API key/OAuth, making it suitable for portals, investor dashboards, and market-analysis tools focused on Southern Europe. However, if you're looking for more capabilities, getting an Idealista scraper is a good idea.
8. Rightmove
Rightmove, the UK’s largest property portal, exposes partner APIs (Real Time Data Feed and Commercial Listings API) that let agents and software providers upload, update, and remove listings via secure HTTPS endpoints using XML/JSON payloads and certificate- or OAuth2-based authentication.
These APIs are designed for listing management rather than open search, so developers who need searchable Rightmove data often resort to using a Rightmove scraper
9. Zoopla
Zoopla, one of the UK’s leading property portals, offers partner APIs for agents and software providers rather than a public search API. Its Client Feed/Export and Real-Time Listings services let you sync listings to and from Zoopla in a standard XML/HTTP format, while additional APIs handle leads and premium listing upgrades. The former public listings API has been retired, and access to live Zoopla data now generally requires a commercial agreement via Zoopla/Hometrack’s data services team.
That's why developers who want searchable content need a Zoopla scraper.
10. Apartments.com
Apartments.com, part of CoStar Group, offers a private partner API that lets property managers and integrated software vendors manage their own rental listings, availability, pricing, photos and reviews.
The API is focused on syncing a customer’s inventory rather than providing an open, public search of all Apartments.com data, so broader market access typically requires a separate Apartments.com api.
11. Google Maps
Google Maps Platform isn’t a real estate listing API, but it’s a core building block for property apps. Developers use the Maps, Places, Geocoding, and Directions APIs to turn addresses into coordinates, display interactive maps, calculate commute times, and overlay nearby amenities like schools, transit, and shops. With pay-as-you-go pricing and broad global coverage, it’s often combined with other Google Maps API to power search, valuation tools, and neighborhood exploration.
12. Homesage.ai
Homesage.ai provides AI-powered real estate APIs covering ~140M+ U.S. residential properties, combining traditional property data with investment analytics
It’s aimed at developers building investor tools, lender workflows, and PropTech platforms that need deeper “should I buy and renovate this?” intelligence rather than just raw listing data.
13. Realtors Property Resource (RPR)
Realtors Property Resource (RPR) is the U.S. REALTORS®-only national property database, offering APIs and integrations that surface tax records, MLS data, demographics, and market analytics inside MLS systems and broker tools.
Access is tied to NAR membership and MLS/vendor partnerships, making it a strong option for REALTOR-centric workflows rather than open public use.
14. SchoolDigger
SchoolDigger provides a K-12 school data API for 125k+ U.S. schools, exposing locations, rankings, test scores, student demographics, and program participation via REST endpoints. It’s commonly used to enrich property search pages with “nearby schools” and performance metrics in U.S.-focused real estate apps.
15. ClimateCheck
ClimateCheck offers property-level climate risk scores and hazard projections (heat, fire, flood, drought, storm) that can be integrated into real estate platforms via licensed datasets and APIs/partners.
It’s aimed at investors, lenders, and portals that want to show long-term climate resilience alongside property details.
16. AirDNA
AirDNA's API exposes proprietary short-term rental analytics: Airbnb/STR supply, occupancy, ADR, revenue, and property-level performance across global markets.
Developers use it to power investment tools, market selection dashboards, and revenue optimization for vacation rentals.
17. RentCast
RentCast is a U.S. property and rental data API covering ~140M+ properties, with endpoints for property details, owner info, AVM/rent estimates, comps, active listings, and local market stats.
It’s a flexible “all-in-one” data source for investor apps, CRMs, and portfolio dashboards.
18. Datafiniti
Datafiniti aggregates residential and commercial property data (structure details, ownership history, tax assessments, and more) into a searchable property API. It’s positioned as a general-purpose data firehose for analytics, valuation models, and bulk research use cases.
19. Data Rabbit API
Data Rabbit API Rabbit is a cloud-based MLS data aggregation platform that normalizes listings and property data from multiple U.S. MLSs into a single API.
It’s designed for portals and proptech products that want broad MLS coverage without managing individual MLS integrations themselves.
20. Walk Score
The Walk Score API returns Walk Score, Transit Score, and Bike Score for a given location, plus related travel-time tools. Real estate sites use it to display neighborhood walkability on listing pages and to let users search/sort properties by walkability.
21. PropertyRadar
PropertyRadar's API exposes deep U.S. property and owner data with 250+ search criteria, including ownership, equity, loan info, and contact data (phones/emails).
It’s geared toward prospecting, list-building, and marketing automations for investors and real estate service providers.
22. Estated
Estated offers a U.S. property data API with parcel attributes, ownership, tax assessments, AVMs, and more via simple JSON endpoints, and is currently migrating onto ATTOM’s infrastructure.
It’s a straightforward choice when you need standardized U.S. property records without managing multiple data vendors.
23. DataTree
DataTree by First American taps into one of the largest U.S. public land records databases, and its corresponding APIs provide property details, recorded document images, AVMs, and transaction histories.
It’s widely used by lenders, title/escrow, and enterprise proptech for high-fidelity public record data.
24. Mashvisor
Mashvisor’s API provides nationwide U.S. investment data: MLS and off-market listings, historical sales, rental comps, and AI-driven analytics for both short-term (Airbnb) and long-term rentals.
It’s focused on “which property is a good investment?” rather than just raw listings.
25. CoreLogic API
CoreLogic API solutions let you plug in its massive property, mortgage, and risk datasets for property details, valuations, market insights, and portfolio analytics. These are enterprise-grade APIs aimed at lenders, insurers, and large proptech players needing highly curated data and models.
26. HouseCanary API
HouseCanary’s Analytics and Portfolio APIs combine public records and proprietary models to deliver property values, rent estimates, comps, neighborhood stats, and portfolio monitoring tools.
They’re frequently used in lending, iBuying, and investor platforms that need fast, model-ready valuation data.
27. REAPI API
RealEstateAPI (often branded REAPI) is a “smart” property data platform with APIs for property search, detail, comps, parcel boundaries, autocomplete, and skip tracing.
It targets proptech startups and data-heavy products that want flexible, developer-friendly access to nationwide real estate data.
28. RentPath API
RentPath (now Rent.) powers brands like Rent.com and ApartmentGuide, and its real estate API is used in partner and reputation-management integrations to exchange rental listing and review data.
Public documentation is limited, but third-party overviews describe it as a U.S. rental and property data API exposed primarily through commercial partnerships rather than a self-serve developer portal.
What Is a Real Estate API?
Imagine a real estate API as your personal gateway to property data. It helps to unlock a world of information: from property listings to insider market insights, ownership details, and even property valuations.
These APIs are essentially your personal data concierge, serving up information in neat packages (usually in JSON format). Of course, you’ll need a special pass (that’s your authentication key) to get in.
Once you’re in, though, you can ask for all sorts of goodies: property searches, in-depth property details, neighborhood scoop, price estimates, you name it! It’s like having the entire real estate market at your fingertips, ready to spill its secrets at your command.
How Do Real Estate APIs Work?
Real estate APIs operate on a request-response cycle. Developers send requests with parameters (e.g., location, price range) and receive structured data responses.
APIs enforce rate limits to prevent abuse, require authentication keys for security, and often paginate large datasets. Data freshness and regional coverage vary by provider, so developers must choose APIs that meet their specific needs.
Why Use Real Estate APIs?
You can use real estate APIs to build search portals, pricing engines, rental analysis dashboards, mapping apps, investment tools, and automated data pipelines.
APIs save time by providing clean, structured data, enabling faster development and better user experiences.
How to Choose the Best Real Estate API
Choosing the right real estate API depends on several key factors:
Data Needs: Identify whether you need listings, valuations, rental data, or neighborhood insights.
Coverage: Ensure the API covers your target geographic regions.
Data Freshness: Look for APIs that update frequently to provide current data.
Pricing: Consider cost models and whether they fit your budget and usage.
Documentation & Support: Good docs and responsive support make integration easier.
Rate Limits: Check request limits and ensure they meet your app’s demands.
Data Quality: Review sample data for accuracy and completeness.
Integration Ease: Prefer APIs with standard protocols and SDKs for your tech stack.
Licensing: Verify usage rights and compliance with legal requirements.
Testing multiple APIs and combining sources when needed can help you build a robust, scalable solution.
