FAQ
Do I need a Kalshi account or API key?
No. The scraper reads public market data without login or an API key; you only need an Apify account.
Can I get price history for a market?
Yes. Use the history mode with Kalshi tickers and set how many days back to go.
How do I filter out illiquid markets?
Set a minimum volume or minimum open interest; thin contracts are dropped before they are written.
Is it legal to scrape Kalshi?
The scraper collects publicly visible market data. Make sure your use complies with local law and Kalshi's terms, and avoid collecting personal data.
How do I get the data into my app?
Use the Apify API, the Python or JavaScript clients, or integrations with Make, n8n, Zapier and Google Sheets.
