Ethereum Foundation Launches Privacy Tool That Cuts the Link Between AI Prompts and Payers

Key points

• The Ethereum Foundation's dAI team launched zkAPI, built with the Open Anonymity Project and running on Ethereum mainnet, with code described as "experimental."
• Users deposit ETH or USDC into a vault, then generate zero-knowledge proofs to obtain temporary, capped API keys without revealing billing identity.
• The foundation said zkAPI does not provide network anonymity, as providers still see request content, IP metadata, and potentially identifying writing style.
