We get our data from a variety of sources, including public records, tax assessors and online listing websites, and process over 500,000 updates daily.
What areas does your data cover?
We have nationwide coverage for nearly all residential and commercial properties in the US, with over 140 million properties in our database.
We also have market data coverage for nearly all US zip codes and cities.

What happens when I exceed my plan's monthly quota?
All of our plans have an additional request overage fee. When you exceed the number of requests included in your plan, you will be charged this fee for each additional request. You can monitor your API usage and quota on your API dashboard.
What can I do with the data I retrieve from your API?
We do not require you to add attribution or RentCast branding to your application.
Do you provide tutorials and support for using your API?
We have comprehensive API documentation with a list of available endpoints, query parameters, response examples and code samples.
