Choosing the best real estate data API in 2025 is harder than ever. Developers, investors, and PropTech teams no longer need just property records or surface-level market stats. They require complete, investment-ready datasets that combine property intelligence, STR performance, LTR rents, comps, valuations, neighborhood analytics, and multi-year historical data. Without this level of depth, underwriting models, automation tools, and revenue forecasts quickly break down.
That’s why the difference between Mashvisor, AirDNA, and Zillow matters. While AirDNA focuses on STR markets and Zillow provides general property lookup, Mashvisor delivers the only fully comprehensive real estate dataset covering property attributes, tax and assessment history, transaction records, STR and LTR analytics, comps, valuations, neighborhood scores, and 36-month performance trends under one unified API. This article breaks down how all three APIs compare so you can choose the right solution for your investment or PropTech use case.
⭐ Why Mashvisor Ranks #1 in 2025
- STR + LTR + full property intelligence in one unified API
- 36-month historical Airbnb performance
- Complete tax, assessment, and sales/transaction history
- Three valuation models (Mashvisor AVM, Zestimate-style, Redfin-style)
- Active + inactive MLS + off-market data with bulk ingestion
- Micro-geographic neighborhood analytics + rental comps at zip code and neighborhood levels
What Is a Real Estate Data API?
A real estate data API is a programmatic interface that allows developers, analysts, and investors to retrieve property, rental, and market data directly into their applications, models, and workflows. Instead of manually collecting information from different sources, real estate professionals use an API to get structured, machine-readable datasets on demand, typically in JSON format.
Real estate APIs can include any combination of the following data types:
- Property data: Structural details, pricing, home characteristics, and listing status
- Rental data: Long-term rents, rental comps, and neighborhood rent distribution
- STR data: Airbnb occupancy rate, average daily rate (ADR), monthly and annual revenue, seasonality, and active STR listings
- Market analytics: Neighborhood scores, rental yields, and appreciation patterns
- Investment metrics: Cash flow, cash on cash return, cap rate, and ROI forecasts
These APIs are essential for underwriting, forecasting, automated investing tools, PropTech platforms, rental arbitrage models, and data-driven decision systems used by real estate investors.
How Does a Real Estate Data API Work?
Real estate data APIs operate through REST-based endpoints that return JSON responses when queried. Developers send authenticated HTTPS requests to specific endpoints, such as /properties, /rental-rates, or /airbnb/listings, and the API responds with standardized, structured data.
Here is a simplified look at how the process works:
- Authentication: The user provides an API key to gain secure access.
- Request: A GET request is sent to a specific endpoint with parameters, such as city, property ID, Airbnb listing ID, etc.
- Response: The API returns a JSON object containing the requested real estate or rental data.
- Integration: The data is ingested into dashboards, forecasting models, valuation tools, databases, or PropTech applications.
- Automation: High-quality APIs support continuous ingestion so that applications remain updated with the latest property and rental data.
While this structure is universal across Mashvisor, AirDNA, and Zillow, the depth, accuracy, and usefulness of the returned data vary drastically between providers. This is why choosing the best real estate data API is so important.
Which Is the Best Real Estate Data API in 2025?
If you need a quick, high-level conclusion without diving into the full-scale comparison: Mashvisor offers the best real estate data API in 2025 for most investors, analysts, and PropTech developers.
While each of the three platforms has its strengths – as well as its weaknesses – Mashvisor delivers the most advanced combination of data accuracy, STR reliability, LTR coverage, property intelligence, investment metrics, and developer-friendly endpoints – at affordable rates.
Here is a short breakdown:
- Mashvisor API: Best overall solution for investors and PropTech teams because it provides accurate Airbnb data, long-term rental rates, property data, neighborhood analytics, historical performance API, and built-in investment metrics.
- AirDNA: Best for STR-only use cases, particularly forecasting and Airbnb competitive analysis, but limited for full-stack real estate platforms or LTR investors.
- Zillow: Best for general property lookup and home valuation data, but not designed for investment analysis or STR vs LTR decision-making.
In simple terms:
- If you invest in or manage rental properties nationally or build investment tools, deal analyzers, PropTech apps, or arbitrage models, Mashvisor is the most complete choice.
- If you only need Airbnb pricing and STR comps, AirDNA is adequate.
- If you want basic property and Zestimate information, Zillow is useful but limited for investment workflows.
The rest of this guide explains in detail the differences between the three real estate data APIs across accuracy, coverage, API endpoints, pricing, and use-case suitability. In this way, you can confidently choose the best real estate data API for your needs.

How Do Mashvisor, AirDNA, and Zillow APIs Compare on Data Accuracy?
Data accuracy is one of the most important factors when evaluating the best real estate data API. Investors and developers rely on precise and timely data to run underwriting models, power forecasting tools, and build decision-making logic. After all, the apps you build and the investment property analysis you conduct are only as good as the data that you feed into them.
Here is how the three platforms compare across short-term rentals, long-term rentals, and property intelligence:
Short-Term Rental Depth and Accuracy
Mashvisor API
The Mashvisor Airbnb API provides highly accurate STR data by combining:
- Observed Airbnb performance indicators, originating from 11+ million active STR listings
- Pricing and availability signals
- Machine-learning validation and smoothing
- Multi-source cross-referencing
- 36 months of historical STR data
This combination produces reliable occupancy, ADR, RevPAR, monthly revenue, and seasonality patterns, making Mashvisor one of the strongest platforms for investment-grade STR analysis and a powerful Airbnb occupancy rate API for developers who need accurate performance signals.
AirDNA API
AirDNA is well-known for its strong STR dataset and is often used exclusively for Airbnb market modeling. Its data accuracy is high for:
- Daily pricing
- Occupancy signals
- Competitive supply
- STR market trends
However, AirDNA does not provide property-level or LTR data, limiting broader investment analysis.
Zillow API
Zillow does not track Airbnb performance and cannot be used for STR modeling.
💡Winner for STR accuracy: Mashvisor & AirDNA
While AirDNA performs well in pure STR forecasting, only Mashvisor connects this performance data with valuations, comps, LTR metrics, and neighborhood analytics – making it far more suitable for end-to-end investment workflows. This makes Mashvisor the best Airbnb data API in 2025.

Long-Term Rental Depth and Accuracy
Mashvisor API
Mashvisor offers nationwide rental rates for 1-5 bedrooms, built using:
- Active LTR listings: 6+ million
- Local rental comps
- Public rental datasets
- Market-level trend modeling
This provides accurate, investment-ready LTR data suitable for:
- Cash-flow modeling
- Rental strategy analysis
- Airbnb rental arbitrage evaluations
AirDNA API
AirDNA does not offer traditional rental rates or comps.
Zillow API
Zillow provides its proprietary Zestimate, which is helpful for a broad directional estimate, but user and analyst feedback consistently note that it:
- Lacks neighborhood-level specificity
- Can be inaccurate in rural or rapidly changing markets
- Is not designed for investment underwriting
💡Winner for LTR accuracy: Mashvisor
Because AirDNA provides no long-term rental data and Zillow’s rent estimates lack investment-grade precision, Mashvisor becomes the only API capable of supporting hybrid LTR strategies as well as realistic rental arbitrage modeling.
Property Data Depth and Accuracy
Property-level data is one of the strongest differentiators between the three APIs. Mashvisor now provides full, investment-grade property intelligence directly through its API, which goes far beyond basic home attributes or listing feeds.
Mashvisor API
Mashvisor aggregates property data from:
- MLS sources: 160+ million MLS listings for nationwide MLS active coverage
- Public records
- Brokerage feeds
- Manually validated datasets
Mashvisor exposes complete property-level datasets through its /get-property endpoint, allowing developers and analysts to pull a full property profile with a single request. This includes:
- Full structural and attribute details: Beds, baths, square footage, year built, lot size, property type, and architectural information
- Tax history: Full record of past tax assessments
- Assessment history: Historical changes in assessed value
- Sales & transaction history: Recorded sales, dates, prices, and ownership changes
- Active nearby comps: MLS and off market comps automatically matched to the property
- Full-resolution images: Complete image sets for each property
- Multiple valuation models:
- Mashvisor estimated Value
- Zillow-style Zestimate equivalent
- Redfin Estimate equivalent
- Side-by-side valuation comparison for quick investor insight
- Property status and MLS metadata
- Neighborhood and zip code-level analytics tied directly to the property (rental demand, cap rate, CoC return, rental comps, etc.)
This level of completeness makes Mashvisor a unique source of end-to-end investment data – from property fundamentals, transaction history, and comps, to valuations, rental performance, and neighborhood analytics – all in one ecosystem.
AirDNA API
AirDNA does not provide property-level data of any kind. Its dataset focuses exclusively on STR performance metrics and market indicators. For those needing valuations, comps, structural attributes, or transaction history, AirDNA requires external data sources.
Zillow API
Zillow provides strong listing-level data and public-record attributes, but its API is limited compared to Mashvisor. Key constraints include:
- No STR data
- No investment metrics
- No rental comps (LTR)
- No tax history or assessment history via API
- No transaction history via API
- No multi-model valuation comparison
- API access is restricted and often requires enterprise agreements
While Zillow has broad listing coverage, it does not provide the depth or investment readiness that Mashvisor’s unified property dataset offers.
💡Winner for property accuracy: Mashvisor
This depth of property intelligence simply doesn’t exist in AirDNA’s STR-only dataset or Zillow’s limited API, positioning Mashvisor as the only provider offering complete property-level data programmatically.
Which API Has the Best Market Coverage? (National & Local)
Market coverage determines how reliably an API can support nationwide investing, expansion into new cities, or PropTech applications that require broad geographic reach. Mashvisor, AirDNA, and Zillow all offer nationwide data availability across the US, but there are some important differences to keep in mind.
Below is a breakdown of how each API performs at the national, city, zip code, and neighborhood levels:
National Coverage
Mashvisor API
Mashvisor offers full nationwide coverage across all 50 US states, delivering STR, LTR, property, and investment analytics for every housing market, no matter how small or big. This makes it suitable for investors analyzing multiple states as well as for PropTech platforms that need broad scalability.
AirDNA API
The AirDNA API also covers the entire US market but focuses exclusively on STR performance. While nationwide for Airbnb data, it lacks long-term rental and full property datasets.
Zillow API
Zillow has one of the largest property databases in the US. However, the Zillow API access is limited, and regional MLS restrictions may affect comprehensiveness.
💡Winner for national breadth: Mashvisor
While AirDNA and Zillow cover large parts of the US, neither delivers the multi-layered investment insights including STR, LTR, comps, valuations, and neighborhood metrics available across all markets through Mashvisor.
City-Level Coverage
Mashvisor API
Every US city is supported with:
- Market-wide STR metrics
- LTR rent distributions
- Property performance
- Analytics and investment scores
- Historical trends (up to 36 months of STR data)
This ensures consistent city-level insights.
AirDNA API
AirDNA offers strong city-level STR data but only within active Airbnb markets.
Zillow API
Zillow delivered city-level property and price data but no STR or investment analytics.
💡Winner for city-level investment analysis: Mashvisor
Zip Code-Level Coverage
Mashvisor API
Mashvisor’s zip code-level coverage includes:
- STR metrics (ADR, occupancy, revenue)
- LTR rents
- Property characteristics
- Investment analytics
- Seasonality patterns
This micro-level granularity is crucial for investors and arbitrage operators.
AirDNA API
AirDNA delivers strong STR insights at zip code levels but lacks LTR and property depth.
Zillow API
Zillow provides zip code-level property data and price trends but no STR or investment metrics.
💡Winner for zip-code targeting: Mashvisor
Neighborhood-Level Coverage
Mashvisor API
The Mashvisor API provides detailed neighborhood analytics, including:
- Rental demand
- STR supply density
- Cash on cash return
- Cap rate
- Rental comps
- STR seasonality
This level of data coverage is vital for local investment decisions, property scoring, and PropTech search engines.
AirDNA API
Investors and developers can access neighborhood-level STR insights in major cities, but not for all neighborhoods.
Zillow API
Zillow comes with limited neighborhood-specific investment data, which is mostly focused on property level and price trends.
💡Winner for granular neighborhood analysis: Mashvisor
How Do Their Mashvisor vs AirDNA vs Zillow API Endpoints Compare?
The quality and variety of API endpoints determine how much you can build with each platform. For investors, analysts, and PropTech developers, endpoint depth affects everything from valuation and underwriting to automated deal-finding tools and market analytics.
Following is a full breakdown of how Mashvisor, AirDNA, and Zillow compare in terms of endpoint availability, usefulness, and flexibility:
Mashvisor API Endpoints
Mashvisor offers one of the most complete and investment-focused API ecosystems in the real estate industry. Instead of providing isolated datasets, the company delivers an end-to-end data pipeline that covers property intelligence, rental performance, comps, valuations, neighborhood analytics, and multi-year historical trends in a single system.

“bathrooms”: 1
}
}
You can check out the Mashvisor API documentation for further examples and details.
This type of standardized, structured JSON makes Mashvisor particularly attractive for real estate investment analysis tools and investment models. The breadth of Mashvisor’s endpoints contrasts sharply with the single-purpose STR focus of AirDNA and the restricted, property-only scope of Zillow, giving developers a unified API for all investment use cases.
Why Mashvisor’s API Is the Most Complete
Mashvisor provides the best real estate data API for various needs and purposes because it:
- Brings together STR, LTR, full property data, valuations, comps, and neighborhood analytics in a single unified API.
- Delivers unmatched 3-year historical STR performance for accurate forecasting and validation.
- Includes full tax, assessment, and sales/transaction history – data that competitors don’t expose programmatically.
- Offers nationwide MLS coverage with active and inactive listings and bulk ingestion for large-scale applications.
- Delivers readily available investment metrics, such as cash flow, cap rate, and cash-on-cash return, which are not available in Zillow or AirDNA APIs.
- Updates data daily for STR metrics and in real time (multiple times a day) for MLS metrics.
How Does Pricing Compare Among Top Real Estate Data API Providers?
Pricing is a critical factor when choosing the best real estate data API, especially for users who need ongoing high-volume access. Mashvisor, AirDNA, and Zillow use very different pricing models.
Let’s take a look at a detailed breakdown of how each one structures its API pricing in 2025:
Mashvisor API Pricing
Mashvisor offers one of the most transparent and flexible pricing structures among real estate APIs. Pricing is organized in a way that supports a wide range of users – from individual analysts with low-volume requirements to enterprise-grade PropTech developers with high-volume requests.
Typical Mashvisor Pricing Features
- Tiered plans based on usage volume
- Access to all major datasets with a single subscription (STR + LTR + property + market analytics)
- Optional enterprise plans with higher rate limits
- Predictable monthly costs
- No upfront licensing fees
Because Mashvisor provides multiple data types under a single API, it tends to offer strong value per dataset compared to STR-only or property-only APIs.
Best for: Developers and investors who want a complete real estate investment dataset without paying separate providers for STR, LTR, and property information.
AirDNA API Pricing
AirDNA pricing is typically higher because it focuses exclusively on short-term rental and Airbnb analytics. While the AirDNA website does not provide pricing information about access to their API, the platform tends to charge per market, which additionally inflates the cost.
Typical AirDNA Pricing Characteristics
- Market-level data priced individually (city by city)
- STR-only datasets
- Higher costs for large-scale API access
- Enterprise plans available but premium-priced
- Limited pricing transparency without contacting sales
For developers who only need STR data, AirDNA can be effective, but for full investment analysis, additional datasets (LTR, property attributes, ROI metrics) must come from other sources, raising the total cost.
Best for: STR-focused researchers and platforms that only need Airbnb data and nothing else.
Zillow API Pricing
Zillow’s API availability changed significantly over the years. Many public endpoints were discontinued, and the company now primarily offers access through the Zillow Bridge API, often under enterprise contracts.
Typical Zillow Pricing Model
- Mostly enterprise-based licensing
- Restricted access for small developers
- Pricing varies widely depending on use case
- Designed for listing distribution, not investment analytics
- No STR or LTR-based pricing tiers
While Zillow provides strong property coverage, the lack of investment-grade datasets makes it less suitable as a full-stack real estate investment API.
Best for: Applications that need property search, listings, or Zestimates, but no STR or rental performance analytics.
Pricing Summary: Which Real Estate API Has the Best Value?
- Best value for investors & PropTech Developers: Mashvisor (broadest dataset per dollar + predictable pricing)
- Best for STR-Only Apps: AirDNA (if Airbnb-focused and budget is less of a concern)
- Best for General Property Apps: Zillow (enterprise-level licensing for large listing platforms)
Once additional data sources are factored in, AirDNA and Zillow often require multiple providers to match what Mashvisor delivers in one subscription, making it the most cost-efficient option for full-stack investment analysis.
Which Real Estate Data API Is Best for Investors?
Each API is designed for different types of investing, but when comparing overall usefulness across STR, LTR, arbitrage, fix-and-flip, and buy-and-hold strategies, the differences become clear:
Mashvisor offers the most complete dataset for investors because it combines:
- STR performance data
- LTR rental rates and comps
- Property attributes and pricing
- Neighborhood analytics
- ROI metrics
- 36 months of historical STR performance
This makes it suitable for investors who analyze multiple real estate strategies or need full-stack analytics in a single API.
AirDNA is a good option for investors focused exclusively on Airbnb or STR modeling. Its STR accuracy is strong, but it lacks property data, rental comps, long-term rates, or investment KPIs. This means that investors still need additional data providers for full analysis.
Zillow is helpful for basic property lookup and high-level rent estimates, but it is not designed for STR or investment-focused workflows. It performs better as a supplemental property reference rather than a full investment API.
💡Final verdict: For most investors – whether STR-focused, LTR-focused, or using a hybrid strategy – Mashvisor is the best real estate data API because it delivers every dataset required for underwriting, forecasting, and analyzing opportunities across multiple markets.
Which Real Estate Data API Is Best for PropTech Startups & Developers?
For PropTech teams, the best real estate data API is the one that offers clean, consistent data structures, broad coverage, and enough endpoint variety to support scalable product development.
Mashvisor is the strongest choice for developers because it delivers STR, LTR, property data, neighborhood analytics, and investment metrics in a single REST API with predictable JSON formatting. This reduces the need to combine multiple providers and simplifies integration for tools, such as deal analyzers, search engines, valuation models, arbitrage calculators, and investor dashboards, especially if you want to build Airbnb revenue model API workflows on top of reliable STR and LTR data.
AirDNA could work for developers building strictly STR-focused applications. Its STR data is reliable, but the absence of property data, rental rates, and investment metrics makes it insufficient for full-stack platforms.
Zillow provides solid property-level information but lacks STR and LTR performance analytics. Its API access is also more restrictive, limiting flexibility for early-stage PropTech development.
💡Final verdict: For developers building investment apps, underwriting tools, or multi-market analysis platforms, Mashvisor is the most versatile and developer-friendly real estate data API in 2025.
Sample JSON Response (For Developers)
Real estate APIs are only as useful as the structure and clarity of the data they return.
To help developers understand what to expect when integrating a real estate API, here is a simplified sample JSON response – just what Mashvisor provides – for property and STR performance data:
{
“status”: “success”,
“content”: {
“property_id”: 12883347,
“smart_location”: “Phoenix, AZ, US”,
“property_type”: “Single Family Residential”,
“bedrooms”: 3,
“bathrooms”: 2,
“list_price”: 397500,
“airbnb_metrics”: {
“occupancy_rate”: 0.72,
“average_daily_rate”: 165.40,
“monthly_revenue”: 3450,
“seasonality_index”: {
“january”: 0.88,
“march”: 1.04,
“july”: 0.93,
“november”: 0.85
}
},
“long_term_rent”: {
“median_rent”: 2100,
“rent_3br”: 2200
}
}
}
This type of structure makes it easy for developers to:
- Parse property attributes
- Run STR or LTR revenue models
- Feed data into valuation tools or dashboards
- Compare multiple markets programmatically
The consistency and predictability of the JSON format is a major factor in determining which platform provides the best real estate data API for scalable development.
Final Verdict: What Is the Best Real Estate Data API in 2025?
After comparing the Mashvisor API, AirDNA API, and Zillow API across accuracy, coverage, data types, endpoint depth, pricing, and developer usability, the conclusion is that Mashvisor offers the best real estate data API in 2025 for investors and PropTech developers.
