DemosOpen protocol · draft 0.1
VXP is an open protocol for that work. The person authorizes what their agent may do with the company, the company does it in its own systems under its own rules, and both keep signed evidence that anyone can check afterwards.
1 · The work
A booking, a sale, a change, a request or a problem. The company already knows how to do it, in its own systems and under its own rules. What changes is who asks.
Retail
Inside the company: check the route and the stock, change the date in the order system.
Hotels
Inside the company: quote the current rate, hold the room, record the guarantee.
Distribution
Inside the company: apply the discount policy, issue the quote, create the order.
Healthcare
Inside the company: find a free slot with the same professional and update the schedule.
Utilities and telecom
Inside the company: open the ticket, assign a visit, report each change of state.
Insurance
Inside the company: check the policy, register the claim, ask for what is missing.
2 · Who asks
The person talks to their agent, on the phone or in a chat. The agent goes to the company to ask for something, to pick up a request already under way, or to answer when the company needs a decision. The company did not build that agent and cannot see its conversation.
Before it acts, the company needs four answers, and so does anyone who checks the work later:
«Move my order to Wednesday.» The agent starts a request with the company.
agent → companyDays later it comes back to the same request, and the company recognizes it.
agent → companyThe company needs a decision and asks the agent, within what the person allowed.
company → agent3 · What VXP adds
VXP does not replace how the company works. It gives the agent and the company a common way to agree on what may be done, to do it exactly once, and to prove it.
The person links their account and authorizes the agent with the company: which operations, on which resource, up to what limit, until when. They can revoke it. Within that agreement the company can also start a request toward the agent.
VXP Relationship
Nothing runs until one exact revision of the terms is accepted. Then it runs once, under the company's own rules. Every implementation meets the operation requirements O1 to O7.
Operation requirements
The request, the terms, the approval and how it was given, the execution and what the company's system showed afterwards, each signed and linked to the one before. Anyone can check the chain.
VXP Proof
Its own profile. VXP has a native profile that needs no other protocol: discovery on the company's domain, the agent's own identity, permission per request, operations, Proof and Relationship.
Optional interoperability. For agents that already speak Poppy or PACT, a company can also publish those adapters, on the same issuer. VXP was created by SOVRAS; anyone can implement it.
4 · One operation, step by step
Order P-1042 at a test hardware store, Ferretería Demo. Each step says what happens; open the messages only if you want to see them. Captured from the reference implementation running the native profile alone, on the evening of 22 October 2026.
Hosts are shown as store.example and agent.example, and long tokens are shortened. Entry-path labels are explained in Conformance.
5 · VXP Proof
The proof of the operation above. Two roles sign: the company signs the terms it offered and the result it declares; the operator, which runs the operation for the company, signs what it received, executed and read back. Choose a statement to inspect it, then try to alter it.
6 · VXP Relationship
In the same consent as the order, the person allowed the store to propose delivery changes to their agent, twice a day at most, for one hour. Within that agreement the store started a request, and the agent answered within what was authorized.
7 · Demonstrations
The step-by-step operation above, and a verifier that checks a real proof in your browser, intact or tampered with. The demos page lists every interactive demo that is published.
DemosOn 21 October 2026, personal agents came in through the Poppy adapter, among them Nova AI, SOVRAS's personal agent in beta, and a third-party web agent, Grok, through the companies' web pages. They moved deliveries, bought and booked with a test store and a test hotel, and the hotel asked a guest's agent to keep or release a booking.
