Our latest #API update introduced new API key security controls to help protect your applications and reduce the risk of unauthorized API usage:

🔒 IP address restrictions
🔒 Endpoint restrictions
🔒 Request logging suppression

We've also published a new #Security section in our API docs covering API key protection, security best practices, and the measures we use to protect our platform.

Check out the highlights on our blog:

A lot of improvements we've made to the #RentCast platform and #API came directly from developer feedback.

New query parameters, additional data points, endpoint improvements, integrations, performance optimizations - many started as customer requests.

We'd love to hear what you'd like to see us work on next! ❤️

If there’s a feature, dataset, filter, or workflow that would make RentCast more useful for your app or business, leave a comment or send us a message.

Stay tuned for our upcoming API release, which will add new API key security settings and restrictions to prevent their unauthorized use and reduce security risk.

Being a part of @ETHGlobal Cannes was a blast!

As a 🍒 on the 🎂I managed to lock in and win the first prize by @ASI_Alliance
as a solo builder.

I ended up building a novel way of bringing #RWA evaluation & data on chain using external APIs like
@zillow

@RentCastApp and even news, feed them into agents by @Fetch_ai to do deep reasoning on the data and then push it crosschain using @LayerZero_Core stack.

Making it available for lending & trading protocols.

Managed to get some swims in between as well 🌞 Thank you all who made it possible!

@Vtrivedy10 Looks great!

Every API should be a tool for LLM agents with MCPs…so I just built one for the @RentCastApp API which lets you access Real Estate data across the US! 🏡🔑

FastMCP turns any function into an LLM-callable MCP tool with just one decorator. With some help from Cursor, Claude Sonnet4, and some agentic web search, I converted every API endpoint from RentCast into an MCP tool so LLM agents can automatically use it when they think they need any real estate data

You can:
- Analyze real estate markets by zip, city, or address
- Get up-to-date property valuations (rent + AVM)
- Explore active sale/rental listings, fetch details for any property or listing
- Integrate it easily with your research workflows because all the major players support MCPs :)

Check out the video, it’s already helping me with some apartment hunting in Philly lol

I’m also working on publishing it as a Remote MCP server (probably on @SmitheryDotAI because they rock for everything MCP) so anyone can use it with 0 setup! But in the meantime it’s totally open source (Github linked below) and works locally so let your agents give it a spin
