AutoSentinel Decision Engine

Overview
AutoSentinel is a deterministic decision engine that provides trustless market intelligence through three powerful interaction modes:

1. Predefined Decision Checks - Common, high-value market analysis patterns
2. API/Bot Interface - Programmatic integration for external systems
3. AI-Powered Natural Language - Translate queries into safe, structured checks

What Makes This Special

• Meaningful Chainlink Functions Usage: Core functionality requires CRE
• AI-Enhanced UX: OpenAI/Google AI/Anthropic for natural language processing
• Trustless Execution: No single server controls data or computation
• On-Chain Verification: Every result has cryptographic proof
• Production-Ready: Deployed, documented, and fully functional

The system is built as a hybrid on-chain / off-chain architecture using Chainlink Functions.

1. Off-chain data aggregation:
   • A Chainlink Functions script (source.js) runs on the Chainlink DON.
   • It fetches real-time data from multiple external APIs (CoinGecko, CoinCap, and Polymarket).
   • The data is cross-validated across sources to improve reliability.
2. On-chain verification:
   • The aggregated results are written on-chain to a smart contract deployed on Sepolia.
   • This ensures the decision score and market intelligence data are tamper-resistant and publicly verifiable.
3. Backend integration:
   • A backend service reads the verified on-chain data and combines it with live Polymarket API market listings.
   • A REST endpoint (/api/oracle-data) exposes the unified intelligence layer.
4. Frontend:
   • The frontend displays the verified on-chain prices, risk score, and Polymarket prediction market data, allowing users to see both the verified oracle output and the underlying market signals.
