Using a room

Open a room, add preview credit, authorize a session cap, then send. A solo room answers every message. After you invite someone, only messages that mention @zker call the model.

A session is a bounded spend. The cap is the most the room can use before you settle. Settling closes the session. In the live protocol that close is a signed usage receipt against the private note.

The proof hides the note id, the deposit link, and the exact balance from the API server. It does not hide the prompt from the provider, and it does not hide your network address. Write names only if you mean to share them.

The Ask desk is a preview ledger. Add, authorize, and settle update local storage. They do not call a wallet and they do not move ETH.

ZkApiVault is live on Ethereum mainnet and on Sepolia. The address belongs to the pinned deployment manifest. This site will not guess it.
