Doing a little experiment. I'm using WeatherXM Pro forecasts to bet on Polymarket weather bets. Will probably need to build some custom tools specific for this use case to actually get an advantage, just playing for now.

Facebook used to have some good prediction libraries for this before LLM were a thing

I was thinking mostly about extracting the info needed. For example, WeatherXM Pro has temperature forecasts per station. But n order to answer "highest temp in NY on this date", you need to pull data from like 100 stations in NY. I mean if you really want to do this professionally, not just put an educated bet.
