Authentication

Pass your key as a bearer token or an X-API-Key header. Keys are emailed on purchase; we store only a hash, so keep the email. Every response carries X-RateLimit-* and X-Quota-* headers, and GET /api/v1/me reports month-to-date usage.

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: 107,318 units across 7,383 buildings in 973 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.
