Ethereum zkAPI Lets Users Pay for AI Queries With USDC, Hiding Identity

The notable move here is architectural rather than technical: separating payment from usage breaks the link that usually makes AI queries traceable, and settling in USDC puts a stablecoin at the center of a privacy-preserving service rather than a speculative one. That matters for anyone who treats on-chain payments as surveillance-exposed, and for stablecoin issuers whose tokens increasingly mediate access to compute. Whether the split actually holds under real usage, and whether similar designs spread beyond this single API, is the open question worth watching.
