The x402 Economic Engine

Every inference, tool call, and agent execution happens through our isolated sandbox, and settles through the x402 protocol: 
┌──────────────┐      HTTP Request      ┌──────────────┐
│   Client     │ ───────────────────────>│   Server     │
│  (Cursor/    │<─────── 402 ───────────│   (Lambda)   │

│              │ ────── x-payment ──────>│              │
│              │   (signed USDC tx)      │              │
│              │<────── 200 ────────────│              │
│              │   (with result)         │              │
└──────────────┘                         └──────────────┘

​
Two-Phase Deferred Settlement

Prevents over-billing on transient failures:
  1. Phase 1 (Validation): preparePayment() verifies JWT + Redis budget, returns settle() callback
  2. Model Invocation: Server calls AI provider
  3. Phase 2 (Settlement): settle() executes only after first valid response
Users never pay for failed requests.

​
Session Keys (ERC4337)

For signature-free “Compose Keys” experience:
  • User grants restricted session key with budget (e.g., $10)
  • Key authorized only for transferFrom on USDC contract
  • Redis tracks real-time usage; blockchain is final authority
  • Revocable on-chain at any time

Summary

Manowar is compose.market’s answer to the gap between AI capability and AI agency. It transforms scattered model calls into coherent, persistent, economically-settled workflows that:
  1. Execute Without Supervision: Plan → Act → Reflect loop with multi-run learning
  2. Remember Across Sessions: Hierarchical memory with safe wipe compression
  3. Operate Proactively: Natural language triggers and lifecycle hooks
  4. Settle On-Chain: x402 micropayments for every atomic action
  5. Run Everywhere: HTTP-native access from any interface, globally distributed
The system is not a wrapper around LLMs - it is a deployment fabric that makes AI agents trustworthy economic actors in the agentic economy.
