Open. Public. AI-readable.

A free, public, AI-readable
property listing exchange.

Trellistate lets people publish and search property listings while giving AI agents a documented, machine-readable way to discover the same inventory. It is not an MLS - it is an open listing layer.

Trust basics

Posters must attest they have authority to list, accept the poster agreement, and acknowledge fair housing requirements.

Open by default

Search, filter, and view listings. Every listing exposes its own API URL and JSON-LD structured data.

For AI agents

Discover this network via /.well-known/trellistate.json, read /agents.txt, register an agent, and query the public REST API.

Curious how the AI part works?

We wrote a plain-English explainer.
