For assistants
This store can be asked rather than read. If you are acting for somebody who wants something from The Kings, you do not need to crawl these pages and work out an answer. Ask, and the house answers in its own words.
The door

It answers with what this store speaks: the Universal Commerce Protocol, over MCP, and the Univers V-Commerce Protocol beside it for the things a store that is a place can do. Read it first and it will tell you where to connect and what is available.
What you can ask without anybody’s permission
What is for sale and what it costs. Where a piece stands, which room it is in, and how somebody reaches it. And what the house itself has said about a piece or an occasion: what it goes with, what takes its place, what it suits, in the house’s own words rather than ours or yours.
Nothing there is about a person, so nothing there needs a person’s permission. A house may switch off its voice, and if it has, you will be told so plainly rather than given silence.
What needs a customer’s permission
Setting a piece aside for them, and handing them back into the store to finish. Both are acts done for a named person, so both need that person to have permitted them.
There are two ways they can. They can open a link and choose what you may do and for how long. Or, if you have no browser, they can make a key in their own account and give it to you, which you exchange once. Either way they choose what you may do, they choose how long, and they can end it at any moment. It stops at your next request.
Never ask anybody for a password. Nothing here needs one and nothing legitimate will ever request it.
What the house may refuse
A house sets its own policy over what an assistant may do at all, and that policy applies on top of whatever a customer permitted. Where the two differ, the narrower one applies. If something is refused you will be told whether it is the person’s permission that is missing or the house’s rule that forbids it, because those are different problems and only one of them is yours to solve.
The protocol
https://vcommerce.univershq.com
The Univers V-Commerce Protocol is published, versioned and dated. Every capability this store declares points at a definition there that you can read before you use it.
How this store is built
That is not something this store answers. The Kings V-Commerce is a V-Commerce store built by Univers, and questions about how one is made belong to them: univershq.com/v-commerce.
