About RentCast

RentCast is an API providing on-demand access to over 140 million US property records, covering owner details, home value and rent estimates, comparable properties, active sale and rental listings, and aggregate real estate market data. Coverage includes most residential and commercial properties in the US, with sale and rental market data available for most US zip codes and cities. Data is sourced from public county records, recorded deeds, tax assessor databases, and online directories, with over 500 thousand record and listing updates processed daily and made available via the API without delays or caching.

The API supports retrieving structural attributes, property features, tax assessment history, and tax amounts for specific addresses, along with property owner names and contact information and sale transaction history. It provides automated valuation model (AVM) estimates for property value and rent based on individual property characteristics and nearby comparables, as well as sales and rental comparables with attributes, listed prices or rents, and distance from a subject property. It also supports searching active sale and rental listings by city or geographic area with filtering options, and retrieving historical price and rent trends, market averages, and listing statistics.

The API offers a free plan with up to 50 requests per month, and paid plans priced by request volume; enterprise plans are available by contacting the company. Data licensing terms permit use for internal business purposes, derivative works, commercial products, internal storage, and distribution to end-users, without a requirement for attribution or branding. Integration options include a Zapier connection to over 6,000 other apps, along with guides for connecting to other platforms and AI tools, code editors, assistants, and agents. Support is available 7 days a week via live chat or email.
