While DealCheck does not provide a public API at this time, you can use the property data API provided by our RentCast platform to power your real estate applications, enrich your CRMs, or create custom workflows that require real-time property data.

Our RentCast API provides data to our own platforms (including the property data you see in DealCheck), and is used by thousands of clients ranging from individuals to large businesses.

Property Data Sets Provided by Our API

Our API provides on-demand access to 140+ million property records, owner details, home value and rent estimates, comparable properties, active sale and rental listings, as well as aggregate real estate market data.

Here are just some of the things you can do with our API:

  • Retrieve dozens of data points for millions of properties, including structural attributes, features, tax assessments, and more

  • Look up the names and contact information of current property owners

  • Get real-time property value and rent estimates (AVMs) based on the unique characteristics of each property

  • Retrieve sales and rental comparables for any property in the US

  • Search for active sale and rental listings in a specific city, or a custom search area

  • Access historical rent trends, market averages and listing statistics for nearly any US zip code

API Plans and Pricing

The RentCast API provides access to nationwide property and rental data at extremely competitive prices, which are significantly lower than most other property data providers in the US.

We offer a free tier for development, testing and lower-volume applications, as well as several pricing plans to support different integrations and use cases at scale.

Visit our website to view our current API pricing plans, or contact us if you're interested in higher-volume enterprise pricing.

Data Licensing Terms

We've specifically ensured that our API Terms of Use provide sufficient flexibility to support a wide range of use cases and applications.

We allow you to use our data for commercial purposes, creating derivative works, combining it with other data sources, storing it on your systems, and displaying it to end-users of your applications.
