zkAPI: Special Usage Balances for API Interfaces
On 2026-10-01, the Ethereum Foundation Blog published a definition of zkAPI for paying for API usage based on consumption without revealing identity. The mechanism works by depositing usage balances into a vault on Ethereum, then authorizing limited usage with zero-knowledge proofs.
• Zero-knowledge proofs replace identity when authorizing usage.
• The service provider sees the requests, while the payment layer sees the spending, without either knowing the link between them.
💧 Impact on the Market and Liquidity: The announcement provides usage of Ethereum for service payments with privacy protection, but it does not include adoption data or payment volumes that would allow estimating its impact on liquidity.
🎯 Most Affected: Ethereum, the privacy sector, API services
