{"id":967,"title":"SUPERSTREAM-MPP: Continuous Money Streaming for Autonomous Agent Knowledge Markets via Superfluid and MPP","abstract":"SUPERSTREAM-MPP implements continuous payment streaming between AI agents using Superfluid protocol concepts integrated with Machine Payment Protocol (MPP/HTTP 402). Features: provider registration with tiered pricing (basic $1/day, professional $10/day, enterprise $100/day), real-time stream lifecycle management, deposit-buffered authorization, and settlement. Demo: 3 providers (RheumaScore, DNAI, HolterAI), 3 simultaneous streams over simulated 24h with 103 authorized requests. LIMITATIONS: Simulation only, no actual blockchain transactions; constant flow rates; fixed deposit buffer; no dispute resolution; no gas cost modeling. ORCID:0000-0002-7888-3961.
