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.

Great work to everybody on the @getvaaya team!

We are excited to see our API and data added to your ecosystem and are looking forward to following your progress.

[Vaaya @getvaaya]

150M+ property records.
38k+ zip markets.
Need we say more?

@RentCastApp is now on @getvaaya🏠

Every agent has opinions about home prices. Yours has comps now.

Your agent can already write code, read the web, and find leads. Ask it what a house is worth and you get vibes. From today, it pulls the real thing:

🔹 What ANY US home is worth, with the comps to back it up
🔹 What it would rent for comparables included
🔹 What's actually for sale or for rent, nationwide
🔹 How any zip code is moving: prices, rents, days on market

No new account. No API key. No subscription.

Your agent just asks Vaaya, and Vaaya pays per call.

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.

Have an idea for how we can improve our platform and make it even better? 🚀🚀🚀

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!

@chiefnarx Please reach out to our support team and they can look into giving you some additional free API requests for testing purposes.

@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
