Kalshi’s help page describes transaction fees that depend on the contract and market. Some markets also charge makers when resting orders execute. The exchange’s current fee schedule and order display govern the applicable charge; a single universal percentage would be misleading.[3]

Data and APIs
Polymarket provides event-contract markets and developer interfaces for discovery, order books, data and execution. Its international polymarket.com service is separate from Polymarket US; the international site currently directs US visitors to the US product and offers a view-only path.
Data and APIs
Predictefy offers normalized prediction-market data, matched markets and execution workflows through an API, SDK, CLI and MCP. Its documentation distinguishes venue-specific capabilities, paper trading and optional live execution. One interface does not imply identical support at every venue.
AI agents
Gina combines a natural-language wallet interface with prediction-market research and trading tools. Its documentation separates a cross-market read-only MCP connection from market-specific write connections. Research access can discover markets and inspect books and positions; execution requires the separate Predictions write interface.
