Kalshi Scraper

Actor: fatihtahta/kalshi-scraper | Price: $4.00 per 1,000 saved markets/events

This actor scrapes market and event data from Kalshi, a U.S. political and economic prediction market platform. It turns search results and specific market listings into structured, analysis-ready datasets in JSON, CSV, or Excel formats. It's built for automation, monitoring, and data analysis workflows.

Key Features

• Flexible Data Sources: Scrape data using search keywords or direct Kalshi URLs (both search pages and individual market listings).
• Structured Output: Returns normalized data with key fields like tickers, titles, pricing (yes_price, no_price), volume, categories, status, and resolution details.
• Built for Scale: Handles pagination automatically and allows you to cap results with maxResults to control costs.
• Developer-Friendly: Output is ready for programmatic use via API or downloadable datasets.

How to Use

Configure the actor run via the Input tab. You must provide at least one data source.

Primary Input Fields:

• searchQueries (array of strings, optional): Keywords to search on Kalshi (e.g., ["presidential election", "inflation"]).
• startUrls (array of strings, optional): Specific Kalshi URLs to scrape. Also accepts targetUrls as an alias.
• targetUrl (string, optional): A single URL for a quick, one-off scrape.
• maxResults (number, default 200): Hard cap on the number of markets saved per query.
• pageSize (number, default min(maxResults, 50)): Number of items fetched per API call (range 1-100).
