ETHEREUM FOUNDATION LAUNCHES ZKAPI FOR PRIVATE API ACCESS

Summary from the TLDR Crypto newsletter

The Ethereum Foundation released zkAPI, a zero-knowledge protocol that lets users access paid APIs without exposing their identity, counterparty, or consumption patterns to any intermediary. Users deposit ETH into a vault, generate a ZK proof, and receive a fixed quota of API access, with payment metadata abstracted away so no on-chain or off-chain trace links usage back to the caller. OA-chat is live with zkAPI integrated, and the design generalizes to any gated API resource beyond AI inference. Prior unlinkable inference schemes leaked payment trails - zkAPI closes that gap by separating payment metadata from identity at the protocol layer.
