Follow Up Boss is another popular CRM and lead management platform that helps real estate teams automate lead generation and engagement, create marketing campaigns, and manage sales funnels.

You can connect our API and property data to Follow Up Boss with Zapier, by using the RentCast and Follow Up Boss Zapier integrations together.

Application Builders

Bubble

Bubble.io is a popular no-code and AI platform for building web apps, dashboards, MVPs, and other software with limited engineering resources, since you can use a visual builder instead of manual coding.

Bubble offers a feature called API connectors, which allows you to call any REST API endpoints in your apps, including the ones provided by our API. See this guide that goes over how to use them in detail.

For each API connector, you'll need to provide the URL of one of our endpoints, your RentCast API key in the X-Api-Key header, as well as any of the query parameters supported by that endpoint. Review the endpoint documentation for an overview of the query parameters it supports and what data it returns.

Replit

Replit is another popular AI-powered app builder that can help you build production-ready applications, websites and dashboards. It has deep AI integrations that allow you to leverage AI tools to help with development.

While Replit doesn't have a plug-and-play solution for calling external APIs, you can use the Python requests library or the JavaScript fetch method to make HTTP requests to any of our API endpoints.

Our endpoint documentation pages provide ready-to-use code samples in both Python and JavaScript that you can copy and paste into your Replit apps.

Lovable

Similar to Replit, Lovable is another popular no-code, AI-powered application and website builder that allows you to start building complex apps starting from a single AI prompt.

The Lovable AI is capable of automatically connecting to third-party REST APIs like RentCast without the need for you to write custom code.

To get started, send the Lovable AI a link to our API documentation (or our LLMs.txt file), and provide some context about which endpoints you'd like to use and what data you need to retrieve. See this guide for more information.

Base44

Base44 is an AI-powered app and website builder that allows users to create full-stack applications, dashboards, internal tools, and other software from natural language prompts.

Base44 offers several options for connecting to third-party REST APIs like RentCast, including custom integrations and backend functions. See this guide that goes over them in more detail.

Using Base44's custom integrations, you can import our OpenAPI spec directly into your workspace and set up authentication using your API key. All apps in your workspace will then be able to make requests to the RentCast API.

Retool

Retool is a low-code application builder for creating internal tools, dashboards, and data apps by connecting external APIs, databases and AI models to prebuilt UI components.

You can connect our API to Retool by creating a REST API resource and using it in queries that power tables, charts, and inputs inside your app. See this guide that goes over how to do this in detail.

Alternatively, you can import our OpenAPI spec directly into your Retool project to simplify API setup and maintenance, and start working with our data in minutes. This guide will help you with this process.

Airtable

Airtable can help you build complex web applications, forms and data hubs using a graphical interface and AI, instead of writing all of the code by hand.

Although Airtable doesn't provide a simple way to call external APIs, you can use Airtable scripting to make requests to our API endpoints using the JavaScript fetch method.

See this guide that shows how to do this with a few lines of code. Our endpoint documentation pages also provide ready-to-use code samples in JavaScript that you can copy and paste into your Airtable apps.

Website Builders

WordPress

WordPress is one of the most popular platforms for building and publishing websites, offering built-in tools for page building, content management, theming, and a large ecosystem of third-party plugins.

The easiest way to connect our API to a WordPress site is by using an existing plugin such as WPGet API, which allows you to configure API endpoints and display returned data using shortcodes or template tags with minimal custom code.

For more custom integrations, you can build a lightweight plugin or extend your theme, and make direct requests to our API using the WordPress HTTP API. This approach provides full control over data handling and rendering logic, and is described in this guide.
