Data actors for prediction-market traders

I build and operate automated trading systems on Kalshi weather markets. These actors are the data pipelines behind that trading, packaged for the Store:

  • METAR & NWS Weather Station Observations - raw and decoded station observations: the data Kalshi weather markets actually settle on
  • Kalshi Weather Markets Data (KXHIGH & KXLOW) - per-bracket prices, open interest, and settlement history by city and date
  • Prediction Market Resolution Evidence Checker - paste a market URL, get the live observation that resolves it, with implied outcome and a confidence grade

Why these are reliable

  • API-only: no browser scraping, no anti-bot fragility
  • Public, unauthenticated sources (aviationweather.gov, api.weather.gov, Kalshi public market data): no credentials to expire
  • Tiny default inputs, fast runs: every actor completes its default run in seconds
  • Pay-per-result pricing: no subscriptions

Found an issue or want a field added? Open an issue on the actor. I check them regularly.
