Connect our API and property data to other apps and services.
The RentCast API is built using REST design principles and returns standard JSON responses, making it easy to connect it with many automation, CRM, AI and no-code platforms.
This guide highlights some of the most popular integrations for connecting our API and data to CRM systems, Excel, Google Sheets, email clients, and other apps and services.
An active RentCast API subscription and an API key are required to use the integrations described in this guide. If you haven't set these up yet, follow this guide to do that first.
Automation Platforms
With Zapier, you can connect our API to 6,000+ other apps, like Microsoft Excel, Google Sheets, Salesforce, HubSpot, BatchLeads, and more.
The RentCast Zapier integration includes 10+ custom "actions" you can use in your Zapier workflows (called "Zaps") that give you access to all of our property datasets and endpoints.
To get started, head over to your Zapier dashboard (create an account if you don't have one), click the create new Zap button, pick a starting trigger for your workflow, and then select one of the available RentCast integration actions as a subsequent step.
Make.com is a popular automation and workflow builder that supports over 2,500 apps and services, and is especially popular for building AI-orchestrated workflows.
To add our API to your Make workflows, use the HTTP app, which allows you to make HTTP requests to third-party APIs, like ours. See this guide for detailed instructions on how to use it.
For each HTTP request, 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.
n8n is an automation platform that specializes in integrating AI agents and AI-powered tools into various workflows, and connecting them to different apps and services.
To connect our API and property data to your n8n workflows, use the built-in HTTP request node with a header auth authentication method.
For each HTTP request, 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.
IFTTT is another popular automation service that supports over 800 apps for building custom workflows and connecting different services.
To use our API in your IFTTT workflows, use webhook queries, which allow you to make HTTP requests that return JSON responses. Here is an FAQ that explains IFTTT webhooks in more detail.
For each webhook, 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.
CRM Platforms
HighLevel is a popular CRM, lead generation and marketing automation platform with built-in tools like email and SMS campaigns, website and funnel builder, and social media management.
You can connect our API and property data to HighLevel with Zapier, by using the RentCast and HighLevel "LeadConnector" Zapier integrations together.
Alternatively, you can integrate our API directly into HighLevel workflows by using the custom webhook action, and providing the URL and query parameters of the endpoint that returns the data you need.
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.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 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 request 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.
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 just an 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 as far as what endpoints you'd like to use and what data you need to retrieve. See this guide for more information.
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.
Developer Tools
PostMan is a popular tool for building, testing and monitoring different APIs and API endpoints.
We maintain a public PostMan workspace and an API endpoints collection that includes a full reference of our available endpoints, their supported query parameters and example responses.
You can follow this guide to quickly fork (or copy) our public collection into your own PostMan account, and start testing our API endpoints and queries either through the PostMan website or desktop client.
AI Code Editors
We provide a Model Context Protocol (MCP) server hosted at , to make it easy for AI code editors and IDEs to interact and integrate with our API documentation and endpoints.
Follow this guide for instructions on how to connect our MCP server and API to AI-powered code editors like Cursor, VS Code, Windsurf and Claude.
The OpenAPI Specification (OAS) is a popular language-agnostic standard for defining and describing REST APIs and HTTP endpoints.
We provide an OpenAPI specification that you can use to import our API definition into API testing tools, code generation services, documentation generators, and other applications that support OpenAPI, including Swagger, Stoplight, and others.
