Why showing requests are a trust decision
A showing puts someone inside a seller's home, and a disclosure package contains details the seller shared for serious buyers. Listing agents already screen callers by phone and email, and both are easy to imitate. As buyers' brokerages automate scheduling, the listing side needs a way to tell a real brokerage's agent from an agent claiming to be one.
How the listing brokerage checks the buyer's agent
The buyer's agent presents its AgenID. The listing brokerage's agent resolves it and re-verifies the operator's signature on the manifest, which names the brokerage that runs the agent. The operator declaration shows as DECLARED at L1_REGISTERED; the illustration then shows L2_DOMAIN_VERIFIED, meaning an authority checked that the operator controls the domain it names.
Because the identity is persistent, the listing side can see that the same agent later asks for a second showing or submits an offer, rather than treating every message as a new unknown.
Access and disclosures stay with the seller's side
Identity does not open a door or a file. What is released, to whom and when follows the seller's instructions and the listing brokerage's policy. Offers, representation and everything a transaction requires remain with the parties and their brokerages.
Today the reference registry at agenid.com issues DECLARED and L1_REGISTERED. The higher levels shown in this illustration require an assertion signed by a root authority key that has not been created yet, so they describe how the protocol works rather than something you can obtain today.
Frequently asked questions
Can an AI agent schedule a property showing?
Many scheduling tools already do. What they usually cannot tell the listing side is which agent is asking and which brokerage stands behind it. A portable identity makes that checkable.
How does a listing brokerage verify an AI agent?
It resolves the agent's AgenID, re-verifies the operator's signature on the manifest, and checks which claims about the operator, such as control of its domain, have been independently verified.
Does verification entitle the agent to the disclosure package?
No. AgenID answers which agent is acting and who declared it. What that agent is allowed to do stays with the business on the other side and with the operator that runs the agent. Protocol v1.1.1 defines no signed authorization object.
Does the listing brokerage need an account with AgenID?
No. Resolution is a public HTTPS request, and the signature check uses standard Ed25519 verification over RFC 8785 canonical JSON. No adapter package is published yet for any real estate platform.
