Market statistics
Market reports that update themselves.
Repliers calculates market statistics on the same search your buyers run: any city, neighborhood, map area, price band or property type, grouped by day, month, year or a rolling 7 to 365 days. What its statistics cover, from docs.repliers.io as of November 10, 2026:
Price trends
Median and average list and sold prices over time, with highs, lows and spread, so a chart shows where a neighborhood is heading.
Days on market
Median and average days on market for active and sold homes, the clearest sign of how fast an area is moving.
Inventory
Homes available, new listings and closed sales for any period, the supply and demand behind every market update.
Sale to list price
How far above or below asking homes sell, the number sellers ask about first.
Price per square foot
Price per square foot, plus property taxes and condo fees, for fair comparisons across homes of different sizes.
By neighborhood or type
Every statistic split by neighborhood or property type in one request, ready for area guides and broker reports.
What the Repliers API does
Live MLS data, with the design left to you.
Repliers calls its API headless by design: it delivers the listings, photos and search, and your website or app decides how they look. What it offers, from repliers.com as of November 10, 2026:
Search and filtering
Real-time listing search with filters for price, beds, baths and property type, and search inside a drawn map area or a radius.
Photos and media
Listing photos, video and floor plans served from Repliers' own media storage and CDN, resized to the size each screen needs.
Saved searches and alerts
Repliers stores your users' saved searches and favorite homes, and sends property alerts with two-way messaging on its Professional and Advanced plans.
Search in plain English
Turns a request like "3 bedrooms near a park under $600k" into a listings search, and AI image search finds homes by what the photos show, such as a white kitchen.
AI value estimates
Property value estimates built with AI and machine learning to reflect market conditions, available as an add-on to any plan.
Webhooks and an MCP server
Webhooks keep your own systems in sync as listings change, and an MCP server connects AI assistants straight to live MLS listings.
What we build on it
Your search, your brand, your leads.
Repliers supplies the data. We build everything a buyer, an agent or a broker sees, and connect it to the way your business already works.
Custom MLS search
Map and list search designed around your brand, with filters for your market, saved searches and a search box that understands plain English.
Branded property pages
A page for every home with its gallery, facts, map and price history, and tour and info requests that come straight to your team.
Mobile and web apps
Home search in an app your clients keep on their phone, on the same data and the same account as your website.
Market reports and broker tools
Live market pages for every area you farm, report dashboards for your agents, and agent and office pages built from MLS rosters.
Leads in your CRM
Every saved search, favorite and showing request goes to the CRM you use, with the home attached and routed to the right agent.
API or IDX plugin
When an API beats an IDX plugin.
An IDX plugin is the fastest way to put MLS search on a website, and for many agents it's enough. Brokerages and teams that want search to be part of their product, inside their own design and their own tools, outgrow it. An API like Repliers gives you the data without the plugin's layout, so nothing about the search has to look like everyone else's.
- Search pages designed for your brand, not a vendor's template
- One account across your website, your app and your CRM
- Features plugins don't have, like plain English search
- Market statistics for your own reports and area pages
How a Repliers build works
From sample data to your live MLS.
- Step 1
Strategy call
We learn your market, your MLS and what buyers, agents and brokers should be able to do, and tell you whether an API or a plugin fits.
- Step 2
Build on sample data
We design and build on Repliers' free Preview plan, which uses sample data, while your MLS reviews access to the live feed.
- Step 3
Connect your MLS
Once your MLS approves the feed, you move to a paid Repliers plan, billed by Repliers, and the same build switches to live data.
- Step 4
Launch and care
We launch, test every search and form, and keep the site running and up to date on our monthly care plan.

Questions
Repliers API questions, answered.
What is the Repliers API?
Repliers is an API for MLS listing data, covering more than 500 MLS boards in the US and Canada as of November 10, 2026. It delivers listings, photos, search and saved searches to any website or app, which is what it means by headless: the front end is yours to design.
Is there a free Repliers plan?
Yes. The Preview plan is $0 a month and uses sample data instead of real MLS listings, so it's for building and testing before you go live. Live data starts on Repliers' paid plans.
Do I need my MLS's approval?
Yes, for live data. Each MLS decides who can display its listings and how. We build on sample data while your MLS reviews the request, then switch the same build to your feed.
Who pays for Repliers?
You do, directly to Repliers, on the plan that fits the features you need. Our build is a project price, plus the monthly care plan every site and app we build runs on.
Are you a Repliers partner?
No. We are a Repliers affiliate: we build on its API, and if you sign up through our link we may earn a commission at no extra cost to you. We recommend Repliers only when it fits your MLS and what you want to build.
Can I see something built on Repliers?
Yes. Our live demo is a custom map search for a fictional brokerage on Repliers' sample data, with filters, plain English search, property pages and market statistics charts.
What market statistics can Repliers show?
Median and average list and sold prices, days on market, available, new and closed listings, sale to list price, price per square foot, taxes and condo fees, over any period and for any search. Sold history can depend on your MLS and your Repliers plan, so we check what your feed includes before we design the reports.
Should I use Repliers or an IDX plugin?
If you want standard MLS search on an agent website quickly, an IDX plugin is usually enough. If you want search inside your own design, an app, or broker tools on the same data, an API like Repliers is the better base.
