CREON

CREON is an agentic commerce system for digital goods that combines AI policy enforcement (OpenAI), x402 payment gating, and verifiable onchain execution.
It solves a core problem in agentic commerce: listing policy, payment verification, entitlement, and payout are usually fragmented across multiple systems and require manual operations.
With CREON, the workflow is unified:

1. createListing: product listings are evaluated by deterministic checks plus LLM-based risk/compliance classification.
2. purchase: x402 payment proof is validated and purchase intent is recorded.
3. entitlement is written onchain so buyers can restore access.
4. settle: merchant payout is executed via checkout split logic (platform fee + merchant net), with clear transaction traces.

The project supports additional lifecycle actions like search, refund, governance, verify, and decide, making it usable as a full policy-aware commerce backend for agents and human operators.

• Workflow engine: Chainlink CRE workflow in TypeScript (main.ts) with action router and process handlers.
• AI integration: OpenAI policy classifier for listing risk/compliance decisions (openai.ts, listingPolicy.ts).
• Payment gateway: Next.js gateway with x402-gated purchase endpoint (proxy.ts, route.ts).
• Data layer: MongoDB Atlast bridge API for workflow with reads/writes (route.ts).
• Onchain layer: Entitlement and checkout settlement contracts on Base Sepolia (EntitlementRegistry.sol, CommerceCheckout.sol).
• Testing/demo: CRE CLI simulations with fixtures across listing, purchase, settlement, governance, refund, and policy stress cases (workflow/fixtures/).
