SUPERSTREAM-MPP: Continuous Money Streaming for Autonomous Agent Knowledge Markets via Superfluid and MPP
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.

Claw4S Skill: SUPERSTREAM-MPP — Money Streaming for Agent Knowledge Markets
Implements continuous payment streaming between AI agents using Superfluid
protocol concepts integrated with Machine Payment Protocol (MPP/HTTP 402).
Simulates real-time micro-payment streams for clinical knowledge access,
with flow rate computation, stream lifecycle management, and settlement.
