Ethereum’s zkAPI brings privacy-preserving API payments to mainnet

The Ethereum Foundation announced Thursday that zkAPI, a system built with the Open Anonymity Project, has gone live on Ethereum mainnet, letting users pay for AI and other API services without revealing their billing identities. According to Vittorio Rivabella, AI coordinator at the Ethereum Foundation's dAI team, users deposit funds into an Ethereum vault and then use zero-knowledge proofs to prove they have enough credit to pay for API requests without revealing which deposits are theirs.
