RentCast

RentCast provides real estate data — property records, rent and value estimates, active listings, and market statistics — for residential properties across the United States. The RentCast API exposes this data through a set of REST endpoints, allowing you to retrieve property details, automated valuation model (AVM) estimates, and zip-code-level market trends on demand.

Power end-to-end data operations for your RentCast API with Nexla. Our bi-directional RentCast connector is purpose-built for RentCast, making it simple to ingest data, sync it across systems, and deliver it anywhere — all with no coding required. Nexla turns API-sourced data into ready-to-use, reusable data products and makes it easy to send data to RentCast or any other destination. With comprehensive monitoring, lineage tracking, and access controls, Nexla keeps your RentCast workflows fast, secure, and fully governed.

Prerequisites

Before creating a RentCast credential, you need a RentCast API key. RentCast authenticates API requests using an API key that you generate from your RentCast API dashboard.

To obtain your RentCast API key, follow these steps:

1. Navigate to the RentCast API Dashboard and create a RentCast account, or sign in if you already have one.

2. From the API dashboard, select an API plan. RentCast offers a free tier that includes a limited number of API requests per month for testing, along with volume-based paid plans that can be changed or canceled at any time from the dashboard.

3. Generate a new API key from the dashboard. Copy the key and store it securely, as it authenticates all requests made to the RentCast API on your behalf.

For complete details about API keys, plans, and usage limits, see the RentCast API documentation.

Authenticate

Credentials required

Field	Required	Secret	Description
API Key	Yes	Yes	API key used to authenticate requests to the RentCast API.

Create a credential in Nexla

1. After selecting the data source type, click the Add Credential tile to open the Add New Credential overlay.

2. Enter a name for the credential in the Credential Name field and a short, meaningful description in the Credential Description field.

3. Enter your RentCast API key in the API Key field. This key authenticates Nexla with the RentCast API and should be kept confidential.

   If your API key is compromised, generate a new key from the RentCast API Dashboard and update the credential in Nexla. For additional information, see the RentCast API documentation.

4. Click the Save button at the bottom of the overlay. The newly added credential will now appear in a tile on the Authenticate screen during data source creation.

Use as a data source

To create a new data flow, navigate to the Integrate section, and click the New Data Flow button. Select the RentCast connector tile, then select the credential that will be used to connect to RentCast, and click Next; or, create a new RentCast credential for use in this flow.

Endpoint templates

Nexla provides pre-built templates that can be used to rapidly configure data sources to ingest data from common RentCast endpoints. Select the endpoint from which this source will fetch data from the Endpoint pulldown menu. Available endpoint templates are listed in the expandable boxes below.

List Property Records

This endpoint template retrieves property records from RentCast. Use this template when you need to access property-level data such as structural attributes, features, and tax history for residential properties.

• This endpoint returns property records and automatically paginates through large result sets, fetching subsequent pages until all available records have been retrieved.

For detailed information about property records, request parameters, and response fields, see the RentCast API documentation.

List Sale Listings

This endpoint template retrieves active sale listings from RentCast. Use this template when you need to access properties currently listed for sale, including listing details and location information.

• This endpoint returns sale listings and automatically paginates through large result sets, fetching subsequent pages until all available records have been retrieved.

For detailed information about sale listings, request parameters, and response fields, see the RentCast API documentation.

List Rental Listings

This endpoint template retrieves active long-term rental listings from RentCast. Use this template when you need to access properties currently listed for rent, including listing details and location information.

• This endpoint returns long-term rental listings for the location and filters you configure.

For detailed information about rental listings, request parameters, and response fields, see the RentCast API documentation.

List Statistics

This endpoint template retrieves market statistics from RentCast. Use this template when you need aggregate market data — such as historical trends, averages, and statistics for a given area — rather than individual property records.

• This endpoint returns market statistics for the location you configure.

For detailed information about market statistics, request parameters, and response fields, see the RentCast API documentation.

List Value Estimate

This endpoint template retrieves a property value estimate from RentCast's automated valuation model (AVM). Use this template when you need an estimated sale value for a property based on its characteristics and comparable properties.

• This endpoint returns an AVM value estimate for the property you configure.

For detailed information about value estimates, request parameters, and response fields, see the RentCast API documentation.

List Rent Estimate

This endpoint template retrieves a rent estimate from RentCast's automated valuation model (AVM). Use this template when you need an estimated long-term rent value for a property based on its characteristics and comparable rentals.

• This endpoint returns an AVM rent estimate for the property you configure.

For detailed information about rent estimates, request parameters, and response fields, see the RentCast API documentation.

Once the selected endpoint template has been configured, click the Test button to the right of the endpoint selection menu to retrieve a sample of the data that will be fetched. Sample data will be displayed in the Endpoint Test Result panel on the right, allowing you to verify that the source is configured correctly before saving.

Manual configuration

RentCast data sources can also be manually configured to ingest data from any valid RentCast API endpoint, including endpoints not covered by the pre-built templates, chained API calls, or custom request parameters. Select the Advanced tab at the top of the configuration screen, and follow the instructions in Connect to Any API to configure the API method, endpoint URL, date/time and lookup macros, path to data, metadata, and request headers.

Once all of the relevant settings have been configured, click the Create button in the upper right corner of the screen to save and create the new RentCast data source. Nexla will now begin ingesting data from the configured endpoint and will organize any data that it finds into one or more Nexsets.
