Average Rent Data API
The rent data everyone else publishes monthly.
Per unit, per day.
100,772 listed units across 6,847 buildings in 899 US cities, refreshed every 24 hours. Real asking rents, concessions, availability, and week-over-week price cuts, one JSON call away.

FAQ
Where does the data come from?
Prices come from each building's public listings and are refreshed every 24 hours, unit by unit. Coverage today: 100,772 units across 6,847 buildings in 899 cities, with per-unit price history back to March 2026.
How is this different from other rent data?
Most rent indexes publish city medians monthly. This API exposes the underlying unit-level observations daily: individual asking rents, concessions, availability dates, and week-over-week price cuts per unit.
How do I get an API key?
Subscribe to a plan and your key is emailed instantly. Payments run through Whop; you can cancel any time and the key deactivates at period end.
Can I show the data in my product?
Yes. Display and analysis in your apps, dashboards, and research are allowed with attribution ("Data: Average Rent" linked to average-rent.com). Reselling or republishing the raw dataset is not.
Is there a free tier?
No free tier, but every endpoint returns a complete sample response on this page, the OpenAPI spec is public, and the Developer plan is month-to-month.
