Ethereum Foundation launches zkAPI to support anonymous AI API payments
PANews October 2 reported that, according to official information, the Ethereum Foundation announced that it is jointly developing zkAPI with the Open Anonymity Project, and that it is already running on the Ethereum mainnet. zkAPI separates payments from identity through zero-knowledge proofs. Users only need to deposit assets such as ETH、USDC into a vault contract on Ethereum once, after which they can authorize AI API to use a spending allowance without exposing their identity. Service providers can see the request contents but cannot learn the payer's identity; payment service providers can see only the spending amount and cannot associate it with a specific request or user. zkAPI operates by having the user's device generate a proof verifying that sufficient funds cover the transaction and that they have not previously been used. After verification, the server generates a temporary API key with a spending limit and validity period. The user can then...
Key points
01
The Ethereum Foundation announced zkAPI, jointly developed with the Open Anonymity Project.
02
zkAPI is running on the Ethereum mainnet.
03
Users can deposit ETH、USDC and other assets into a vault contract on Ethereum in a single transaction.
04
zkAPI allows users to authorize AI API to use a spending allowance without exposing their identities.
05
Service providers can see the request contents but cannot learn the payer's identity.
06
Payment service providers can see only the spending amount and cannot associate it with a specific request or user.
07
The user's device generates a proof to verify that sufficient funds cover the transaction and have not previously been used.
08
After verifying the proof, the server generates a temporary API key with a spending limit and validity period.
AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
zkAPI can be understood as a privacy payment method for AI interfaces. The user first deposits assets into an on-chain vault, and the device then proves that sufficient funds are available for the transaction and that they have not been reused. Once verification succeeds, the server issues a temporary API key subject to spending and time limits. In this way, the party providing AI services and the party processing the payment can each see only part of the information.
Why it matters to readers
The scheme attempts to prevent a single participant from simultaneously possessing the request contents, payer identity, and spending amount, thereby providing AI API with an authorization method that separates identity from payment information.
Beginners should focus on points: this does not mean that no payment is made; rather, assets are deposited first and a temporary spending allowance is then obtained. “Anonymous” means that the information visible to relevant participants is separated; it does not mean that the original text has proved that users cannot be traced through every step.
Risks and unknowns
The evidence is PANews' account of official information; it does not provide the original official announcement for verification.
The main text is truncated at “The user can then...”; the complete operating process and technical details are unknown.
The original text does not provide the vault contract address, code, audit status, or security verification results.
