Ethereum Foundation and Open Anonymity launch zkAPI: pay for AI APIs with zero-knowledge proofs
kenziyuliu · x · 2026-10-02
The Open Anonymity Project, built with the Ethereum Foundation, has launched zkAPI on Ethereum mainnet: users deposit credits into a vault once, then authorize each metered API call with a zero-knowledge proof, so the provider sees requests and the payment layer sees spend — but neither can link them to an identity. A companion product, OA-chat, is now open for signup.
