Payment privacy does not make the contents of an AI conversation private.
The announcement
In a 1 October post, the Ethereum Foundation said zkAPI was running on mainnet. Built with the Open Anonymity Project, it uses funded credits and zero-knowledge proofs to authorise metered API access without linking the payment to a conventional billing identity.
What remains visible
The announcement distinguishes payment privacy from network anonymity and content confidentiality. A provider can still see prompts; IP addresses, timing and repeated personal details can connect sessions.
Why developers are watching
Separating service access from persistent accounts offers an alternative billing design for APIs and agents. The practical questions are integration complexity, provider support and the complete privacy threat model. CoinEditorial has reviewed the announcement, not independently tested the system.
