Watch an AI agent pay a paywalled API, without revealing the amount or the recipient.

Each click below triggers a real on-chain spend through the Umbra mixer. The agent debits its encrypted balance, lands a UTXO commitment in the mixer tree addressed to the merchant, and the merchant claims it asynchronously — so the on-chain link between payer and payee is broken, and the amount stays encrypted.
