Accessing our Sample Data for Prototyping Purposes
This article explains how you can access our APIs for development purposes, including the most common questions we receive about our sample data set and the necessary licensing requirements when you're ready to subscribe to our services.
Sample Data Access
For developers who are in the initial stages of application development and do not wish to pursue a paid subscription, Repliers offers the option to access sample data. This sample data is designed to help you build and test your application’s functionality without the need for a full membership or subscription or to meet licensing requirements.
To request access to our API with sample data, create an account. An API key will be created for you immediately. This data should suffice for testing and developing a working prototype of your application.
Clarifications about Sample Data
Repliers provides a comprehensive sample dataset that allows developers to prototype and test integrations with our API before connecting to production MLS data. This article addresses common questions about our sample data and how to effectively use it for development purposes.
Data Quality & Authenticity
Is this real MLS data or synthetic/mock data?
Our sample data is adapted from real-world MLS data and designed to closely mimic every aspect of actual production feeds. This ensures you're working with realistic scenarios rather than artificially generated information.
Are the property addresses, prices, and details realistic?
Yes. Property details including addresses, prices, and listing information are based on historically accurate values for their respective locations, providing a realistic dataset for development and testing.
How current is the sample data?
While the sample data doesn't have the real-time dynamics of a live MLS feed, we perform regular maintenance to keep it current. Monthly date field related updates ensure the data maintains freshness and doesn't become stale.
Coverage & Scope
Which geographical areas are included in the sample data?
We currently cover regions throughout the United States. We're expanding coverage in iterations, ensuring each new region meets our quality standards before being added to the dataset.
Which MLS boards does the sample data represent?
The sample data is intentionally not associated with specific MLS boards. It's designed as a board-agnostic sample set for advanced prototyping, allowing you to focus on building functionality without being tied to any particular board's characteristics.
How many listings are included in the sample data?
The dataset currently includes tens of thousands of listings, with continued expansion in carefully managed iterations to maintain consistent quality.
Does the sample data include all property types?
Yes. The distribution includes residential, commercial, and condo properties, providing comprehensive coverage for diverse development needs.
Are both active and sold listings included in the sample data?
Yes, the sample data includes both active and sold listings.
I'm developing for a region not covered by your sample data. How should I handle this?
The Repliers API is designed to be region-agnostic. Building for a different region will primarily differ in the specific addresses that can be queried, but the overall development experience and API behavior remain consistent. This means you can still effectively prototype your application using the available sample data.
Is there a specific geographical area you recommend for testing?
We recommend using aggregates functionality to map out the coverage and identify areas with the most extensive data for your testing needs.
Example:
POST https://api.repliers.io/listings?aggregates=city&listings=false
Data Structure & Fields
What fields are populated in the sample data compared to production?
The sample data includes all essential fields necessary to prototype a compliant application. While field availability can vary between MLS boards in production, our sample data captures the core fields you'll need with realistic values.
Does the sample data include nested object structures like media, open houses, and rooms?
Yes, the sample data includes all relevant nested object structures such as media, open houses, rooms, property estimates, and other complex data relationships.
Are images included with the sample listings?
Yes, we include realistic images with sample listings, allowing you to develop and test media display functionality.
Does the sample data demonstrate the full range of status codes and property states?
Yes, the coverage in terms of data variability is excellent, including the full range of status codes and property states you'll typically encounter in production.
Testing & Development
Can I use the sample data indefinitely for development?
Absolutely. There are no time restrictions on using the sample data while building and refining your integration.
Will the sample data change or remain static?
The sample data maintains a relatively stable structure while avoiding staleness through monthly date field updates. These updates introduce some variability without creating the constant flux of a production feed.
How do I switch from sample data to production data in my code?
No code adjustments are typically needed. API calls are identical regardless of the data feed type, so your application will seamlessly transition from development to production environments.
Can I filter and search the sample data the same way as production?
Yes, all filtering and search capabilities work identically with sample data as they do in production.
Can you provide a trial period with production data, even if there's a cost?
Since our subscriptions don't require long-term commitments, a single paid month represents a low-risk investment if accessing production data is essential for your development process.
Limitations
Are there rate limits on sample data access?
Yes, sample data access is subject to a rate limit of 1 request per second (1 RPS).
Can I publicly display sample data results?
Yes, you're permitted to publicly display results from the sample data.
Does sample data support webhooks and real-time updates?
Webhooks are supported for testing CRUD operations and integration mechanics. However, webhook callbacks occur differently than in production due to the limited dynamics of sample data. Updates happen monthly without the continuous stream of new listing events or saved search matches that characterize production feeds.
Summary
Repliers sample data provides developers with an exceptional foundation for building real estate applications—offering tens of thousands of realistic, historically accurate listings across all property types with complete field coverage, nested objects, and media assets, maintained through regular updates and available indefinitely at no cost, all while ensuring a seamless, code-free transition to production data when you're ready to launch.
Licensing Requirements
Once you have validated your application with our sample data and are ready to integrate real MLS® data, you will need to meet our licensing requirements. To access and utilize real MLS® data through our APIs, proper licensing is mandatory. This ensures compliance with the regulations and standards set by the MLS® Systems.
