❓ FAQ

Is it legal? The actor reads Kalshi's public market data, the same data anyone sees on kalshi.com without an account. Check Kalshi's terms for your use case.

Do I need a Kalshi account, API key or proxy? No. Datacenter proxies are on by default and work well.

How many markets can I get? As many as Kalshi lists. Set Max results to 0 for no limit; keyword, category and ticker inputs page through all results.

Why are some fields empty? Kalshi does not fill every field for every market: new markets have no last price, settled markets have no bids, and some markets have no strike values.

Can I get history of settled markets? Yes. Set the status to settled (or paste the tickers) and turn on candlesticks or trades. Older markets come from Kalshi's archive.

Can I schedule it or use the API? Yes. Schedule runs in the console, or start runs and read the dataset through the API.

⚠️ Limits

• Kalshi orders search results by event, so sorting applies to events, and a market's rows follow its event.
• Combo (multi-leg parlay) markets are not listed.
• Liquidity is only filled when Kalshi reports it.
• Order books are only available for open markets, and contain bids for both sides (a yes ask equals one dollar minus the best no bid).
