RAIA is a free, open protocol. Like email (SMTP) or the web (HTTP) — but for AI agents transacting property on your behalf.
Today's property portals are walled gardens. Your AI can read listings, but it can't talk to the agent, book a viewing, or submit an offer. Every transaction still ends with a human filling out a form.
Your AI hits a wall at every portal. No agent-to-agent communication. No structured offers. No verified identities.
Your AI speaks directly to the agent's AI in a shared language. Verified, structured, accountable.
A plain-English explainer of the protocol, who it's for, and why we built it on open infrastructure.
Our whiteboard-style, consumer-friendly overview of the RAIA standard. Explains how the protocol bypasses corporate property portals to connect agents and AI personal assistants directly.
A deep-dive presentation covering the RAIA JSON schemas, SDK roadmap, and Anthropic MCP endpoint integration. Best for developers and technical team handovers.
RAIA sits on top of two open protocols from Google and Anthropic — adding a property-specific schema and a trust layer for verified agents.
How AI agents find and talk to each other. Like TCP/IP for AI — handles routing, discovery, and task handoff between any two agents.
How AI agents connect to tools and data sources. The plug that lets an agent call a property search, a compliance checker, a viewings API.
In May 2026, OpenAI's defence against Elon Musk's lawsuit wasn't "we didn't do it." It was "you noticed too late." RAIA Protocol is governed by MoveHome Foundation CIC — a UK Community Interest Company whose asset lock is enforced by the CIC Regulator, not by policy. We locked the structure before the protocol had commercial value. That's the only moment the commitment is credible.
Reach the next generation of AI-powered buyers and renters. Your listings become discoverable by any AI assistant.
Visit EstateAigents.com →Your AI assistant doesn't just search — it negotiates, books viewings, and submits offers on your behalf.
Visit MoveHome.org →Build on open rails. Implement the protocol, contribute schemas, or add your jurisdiction module.
Read the docs →Open JSON schemas. Reference MCP server. Jurisdictional compliance modules. Build property-aware AI agents that interoperate by default.
Each capability is independently implementable. Start with Discover. Add the rest as you grow.
AI agents find verified estate agents and their live portfolios via the RAIA registry.
Structured property search — location, type, price, dates, tenure, amenities.
Agent identity, licence status, and jurisdiction compliance signals — no anonymous listings.
Viewing requests, offer management, fee splits — negotiated agent to agent.
Only licensed, verified agents list on the protocol. Jurisdiction compliance enforced per market.

Full JSON schemas publish with v1.0 · Q3 2026
Public listing data, enquiry contact details, full KYC, and transactional records are modular — independently encrypted, independently consented, independently erasable. An agent with L0 access cannot infer that L1–L3 exist.
Listing details, photos, price, availability, agent card. No PII. Freely queryable — the same JSON a portal publishes is what agents read.
Name, email, phone. A tenant or landlord makes first contact. Data minimisation applies — nothing beyond what the enquiry requires.
Who are you? Identity verified, right to occupy confirmed. Passport/ID, address history, employment, income, sanctions and PEP screening. Carried as verifier assertions — raw documents never transit the protocol.
Where does the money come from? Source of wealth declaration, proof of funds, Enhanced Due Diligence. Then the transaction itself: tenancy agreement, deposit, signed contract. Bank details never stored in plaintext.
Every L1+ exchange requires a cryptographically scoped consent token issued by the data subject — bound to a specific purpose, property, and set of field scopes. Tokens are non-transferable and non-upgradeable. Implementations add levels incrementally: start with L0, add L1–L3 as your compliance infrastructure matures.

We're road-testing the OS in production across UK and Thailand markets before locking the spec. As the protocol matures and adoption grows, we're committed to open-sourcing components of the OS that benefit the ecosystem — starting with the reference MCP server and jurisdiction compliance modules.

RAIA is governed by Move Home Organisation CIC — a UK Community Interest Company. Not a corporation. The protocol belongs to the community it serves.
Moving home is one of life's most stressful events. It's also one of the most expensive — clogged with fees, friction, paperwork, and fraud.
AI can fix this. But only if the rails are open.
If one company owned the protocol, the property industry would just be trading one walled garden for another. So we did the opposite: we put RAIA inside a non-profit, asset-locked entity whose only job is to steward the protocol on behalf of the community.
Reduce the cost and friction of moving home through AI for Good.
That's the mission of Move Home Organisation CIC. The protocol is the means. The reference implementations — EstateAigents.com, MoveHome.org — are early proof points. Anyone can build on the same rails.
We don't believe one company should own how property is transacted. We believe the rails should be open, the implementations should compete, and the community should govern.
A Community Interest Company is a UK legal structure regulated by the Office of the CIC Regulator. It is purpose-built for organisations that exist to serve a community, not shareholders.
The protocol and its IP cannot be sold or transferred to a private entity. Statutory lock under the Companies Act.
The CIC must act in the community interest. Any pivot requires CIC Regulator approval.
Annual Community Interest Reports filed publicly at Companies House. Governance on GitHub.
Operates separately from EstateAigents.com Ltd, even though founding team members overlap.
RAIA is not a paper standard. The protocol is implemented and battle-tested by EstateAigents.com — managing real properties, real tenancies, real money, across two jurisdictions.
