Polymarket Alert Service

A prediction market monitoring service that combines Chainlink CRE workflows with x402 micropayments. Users can subscribe to custom alerts using natural language (e.g. "Alert me when Trump odds exceed 60%") and get notified when conditions are met. Supports multi-condition alerts, smart keyword extraction, and bulk pricing discounts. Solves the problem of manually monitoring prediction markets by automating price threshold tracking through Chainlink orchestration.

Built with Bun/TypeScript using Hono as the API framework. The CRE workflow polls Polymarket CLOB API every 5 minutes to check alert conditions. x402 protocol handles micropayments (0.01 USDC per alert) on Base L2 via ethers.js. Natural language parsing extracts market keywords, thresholds, and conditions without requiring an external LLM.
