Private AI chat, paid with a zipped note.
Fund a fresh address that only this browser controls, deposit it into zkAPI's vault, and talk to the models directly. No account. No wallet connection. Nothing to log in to.
1. Fund this chat
creating a key…The same signature zipcoin.cash asks for. It derives your zip key in this browser and nothing is sent anywhere; your wallet signs a message, not a transaction, so nothing links it to this chat on chain.
2. Deposit into zkAPI

How it stays private
- The funding address is a throwaway key made here. A zipped note reaches it with no link to your deposit; the relayer sees a proof, not you.
- The vault deposit is signed by that key. The chat then proves “a funded note” to zkAPI's server and gets a 5-minute capped key; prompts go from your browser to the model provider directly.
- This site never sees prompts, answers, the note or the key. It serves the page and passes prompt-free protocol messages to zkAPI's server, which does not accept browsers from other origins yet.
- What the provider sees: your prompt text and your IP. Use Tor or a VPN if the IP matters to you.
