What is weather-prediction?

This is an automated trading bot built for Polymarket, a prediction market platform where users bet on real-world outcomes. Specifically, it targets Polymarket's daily temperature markets, where traders bet on whether a city's highest temperature on a given day will fall within a certain range. The bot works by pulling weather forecasts from two sources: the National Weather Service for US cities and Open-Meteo for international locations. It then looks up the corresponding Polymarket temperature-range betting market for each city, checks whether the current price looks favorable against your entry thresholds, and either reports the signal, simulates a trade, or places a real order on the blockchain. You would use this if you want to automate weather-based trading on Polymarket without clicking through the interface manually. It supports three modes: a read-only signal mode that just prints what it would do, a paper trading mode that simulates trades against a local ledger, and a live execution mode that places actual orders using your connected wallet. The bot can run continuously on a timer, checking prices every 30 minutes. It requires a funded Polymarket wallet, your wallet private key, and network access to the weather and market APIs. Built with TypeScript running on Node.js, targeting the Polygon blockchain network.
