ZKErStart
The desk
ZKEr is a shared thread for model calls. The thread can hold one person or a hundred. The spend is a private note, not a shared login.
What you are opening
A room is the unit of work. Messages stay in that room. A mention of @zker is the moment a model is called. Until that mention, people can talk without spending anything.
Alone, the desk can answer each message, because there is nobody else to address. After a second person sits down, the mention is required. That keeps ordinary conversation from burning the note.
What this website is
The marketing site and the Ask desk are a preview of that room. Credit you add in the browser is stored on the device. Authorize, spend, and settle update that local ledger. They do not broadcast a transaction and they do not move ETH.
The live path is the zkAPI vault on Ethereum. A deposit becomes a private note. A proof opens a short lived key. The provider receives the prompt. A signed receipt settles the measured use. This guide describes both, and it labels which one you are looking at.
What the mark is not
$ZKER is an access mark for the desk. It does not pay interest, a dividend, or a share of fees. No contract address is published here. A future deposit credit for holders, if it is issued, spends like the rest of the note. It is not yield.
