Kalshi
Connects Claude to Kalshi's prediction markets with real trading capabilities. You get six tools: search markets by keyword, pull full orderbook depth, check your portfolio balance and positions, find trending markets by volume, place limit orders, and query entire event series like Fed rate decisions. Built on production auth code from the author's live trading bot, so it handles RSA-PSS signatures and rate limiting properly out of the box. Useful when you want to research political or economic events through market prices, track positions without opening the web UI, or execute trades conversationally. Requires API credentials from Kalshi and a private key file on disk.
