Pulls GFS ensemble weather data for 12 cities with a focus on finding edges in prediction markets. You get access to probabilistic forecasts that can reveal when consensus weather predictions might be off, which matters if you're trading on weather-dependent outcomes or trying to spot mispriced contracts on platforms like Polymarket or Kalshi. The server surfaces ensemble spread and model agreement metrics rather than just point forecasts. Reach for this when you need programmatic access to weather uncertainty data for quantitative trading strategies, not for general weather lookups where a standard API would do fine.
