This technical disclosure describes novel architectural combinations implemented in a metered AI service marketplace protocol deployed on Base L2 (chain ID 8453, production deployment March 28, 2026). It documents six prior art claims: (1) a permanently self-contained reserve-integral bonding curve AMM with solvency-preserving fee extraction,USDC denomination, and decoupled service-revenue routing; (2) cryptographic output commitment for AI inference proxying with dual-modal metering; (3) UUID-scoped OAuth 2.0 Token Exchange (RFC 8693) for agent authorization; (4) DAO-governed ISO jurisdiction mapping with atomic legal reserve extraction; (5) a metered zero-knowledge proxy with dual-modal content commitment and HMAC-signed webhook delivery; and (6) user-signed smart contract deployment with backend receipt verification and zero backend key exposure. Version 2.0.0 supersedes v1.0.0 (DOI: 10.5281/zenodo.18911878, March 8, 2026). This document is published as a defensive prior art record to preserve freedom to operate and prevent third-party patenting of the described systems.
